Under Pressure! 10 At-Home Science Experiments That Harness Air

If the at-home orders have you scrambling for indoor activities , we’ve got easy science experiments you can pull out at a moment’s notice from the comfort of your home. Each kids science experiment reveals air’s invisible power, and (usually) uses what you’ve got in the recycling bin to demonstrate it. Read on to learn how to levitate water, submerge tissues without getting them wet and suck an egg into a jug using only a match.

Keep it Simple

Thankfully, science experiments don't have to be super complex or time consuming. These easy-peasy experiments only require a little prep and leave a big impression on tiny minds. Plus, we’re betting most of what you need to test these theories is already lying around your house.

1. Sink or Swim. Instead of bobbing for apples, your tiny tot will make straws dive and surface with a gentle squeeze. The Kids Activities Blog  lays out the important deets for this hands-on experiment that uses a two-liter bottle and play dough to fully certify straws as scuba-ready. Take the dive into serious science with this one!

Why it works: Squeezing the bottle increases the air pressure inside the bottle and forces water up into the straw, which makes it heavy enough to sink.

2. Blow Their Minds . Bet your cutie a clean room that she can’t blow a rolled up piece of paper towel into an empty bottle. Sounds like a safe bet, right? But thanks to air pressure, the cards are definitely stacked in your favor. To set up the experiment, place an empty two-liter bottle on its side. Ball up the corner of a paper towel that’s about half the size of the bottle’s top and place it just inside the opening then challenge your little scientist to blow the paper towel into the bottle (Trust us, it can’t be done). No matter how hard she tries, she’s not going to win that bet. Learning plus a clean room? We’ll take it!

Why it works: Even though you can’t see it, that bottle is full of air; when you try to blow something into it, there’s just no room.

3. Be Unpredictable. Two balloons, a yardstick, string, and a hairdryer are all you need for this experiment that will keep your mini me guessing. To get things moving in the right direction, blow up the balloons to the same size and then use the string to attach them, a few inches apart, to the yardstick. Once you’re all set up, ask your kidlet what will happen to the balloons when you aim air from the hair dryer between the two balloons. The obvious answer? They’ll be blown apart. But once your wee one takes aim, she’ll see that the balloons are actually pushed together rather than apart. Who knew?

Why it works: Blowing air between the balloons lowers the air pressure and makes the pressure surrounding them higher, pushing them together.

4. Levitate Water . You won’t need to incant Wingardium Leviosa with perfect pronunciation to suspend water during this exciting experiment. Start by filling a glass of water about 1/3 full, then cover it with a piece of cardstock. Tip the glass over, keeping the cardstock in place with your hand, and hold the whole shebang over your unsuspecting kidlet’s head (or a sink if you want to do a test run first!). Then slowly let go of the cardstock while your mini me waits excitedly below. Look ma, no splash! The card stays in place and your little guinea pig stays dry.

Why it works : The outside air pressure working against the cardstock is greater than the weight of the water in the glass.

5. Grab a Tissue. To be wet or not to be wet is the question answered in this simple experiment full of drama. To set the scene, loosely crumple a tissue so that when you stick it in a small glass and turn it over the tissue doesn’t fall out. Then, have your little lab assistant fill a bowl with water, turn the glass over and submerge it completely (psst… keep the glass parallel to the water to make the experiment work). Ta da! The tissue stays dry even when it’s below the water line.

Why it works: The air pressure inside the glass is strong enough to keep the water out and the tissue dry.

Complicate Matters

Get mom or dad in on the action with these experiments that take a little more time and some helping hands to demonstrate just how powerful air pressure can be.

6. Blast Off. Nothing makes air pressure more tangible than a classic bottle rocket  launched on a sunny summer afternoon. You and your sidekick can spend time fashioning a plastic bottle into a space-worthy vessel with a cone top and flamboyant fins on the side. Then, hook it up to the air pump and let her rip! Up, up and away! Science Sparks has simple instructions you can use (and even a cool video!) to make one with your budding scientist.

Why it works: Pumping air into the bottle builds up pressure until you just can’t add any more and all that force sends the rocket flying.

7. Make Eggs Magical. This “look ma, no hands, wires or mirrors” trick will get them every time; an egg being sucked into a jar while your little scientist delightedly looks on is always a hit. To perform this illusory feat, you’ll need a glass jar with an opening just smaller than an egg (think: old school milk jug) and a peeled, boiled egg. When you and your Little have checked these items off your list, it’s time to start the show. Mom or dad should toss a lit match into the glass jar, followed by your mini lab assistant, who’ll quickly set the egg over the opening. Abracadabra! Alakazam! The match dies out; the egg gets (seemingly) inexplicably sucked into the bottle. And just like that you’ve performed another bit of parent magic without breaking a sweat.

Why it works: The match uses up the air inside the bottle. Once that happens the pressure outside the bottle is greater and pushes the egg down into the bottle.

8. Build a Barometer. The invisible air pressure around us is always changing, but try explaining that to the tot lot. We've found a seeing-is-believing DIY barometer experiment to turn the tides for your tiny skeptic. Not only will you reveal ever-changing air pressure, but you can also predict any summer storms heading your way. Get all you need to know about making your own version using a screw-top jar, rubber bands and a straw at Wonderful Engineering .

Why it works: When the air pressure is high, it pushes down on the straw tilting it up, and when it’s low, pressure inside the jar pushes up against the straw pointing it down.

9. Inflate Marshmallows. Put those marshmallows you’re stockpiling for summer s’mores to good use in this DIY vacuum experiment. To make the vacuum, use a hammer and nail to pierce a hole (big enough to fit a straw) into the lid of a screw-top glass jar. Next, stick a straw ever-so-slightly into the hole and seal the edges with play dough or molding clay so there’s no way for the air to get out other than through that straw. Now you’re ready to see what happens to a marshmallow when it’s trapped inside; place the marshmallow in the jar, screw the top back on, and have your mini me take the air out gulp by gulp through the straw (just be sure to cover the straw hole between breaths so no air makes it back in). As the air is removed, the marshmallow expands, like a nightmare vision straight out of Ghostbusters . Who you gonna call?

Why it works : When you use a straw to remove all the air from the jar, there’s no air left working against the marshmallow. Instead, the air trapped inside the marshmallow is able to expand.

10. Pit Balloons Against Bottles. Is your future scientist ready for another challenge? Just like blowing a paper towel into a jug, this science experiment from Steve Spangler Science  is oh-so-much harder than it looks. To entice your little experimenter, place an un-inflated balloon into an empty plastic bottle and ask him if he thinks he can blow it up. Easy right? But no matter how hard he tries, that balloon just won’t fill with air! The trick to inflating the balloon  is a simple one that takes mom or dad’s helping hand and just like that, what was once impossible becomes possible!

Why it works: At first, the bottle is full of air so there’s no room for the balloon to expand when you try to blow it up. But when you try this experiment after the trick, there’s an escape route for the air inside the bottle, leaving room for the balloon to inflate.

Get ready to harness the power of air and amaze your friends with these 7 hands-on science experiments that make the invisible force of air pressure come to life right before your eyes! You'll witness a marshmallow compress inside a bottle, make a cup stick to the table with suction, race balloon-powered cars, suck an egg into a bottle, crush a can with atmospheric pressure, build your own hovercraft, and levitate a ping-pong ball in midair. These engaging activities will spark your curiosity about the fascinating world of air pressure and the science behind everyday phenomena. Let's plunge into and discover more!

Table of Contents

The Mighty Marshmallow

Harnessing the power of air pressure, the Mighty Marshmallow experiment is a fun and engaging way to demonstrate this invisible force. You'll need a clear, narrow bottle, a marshmallow, and a straw.

Begin by placing the marshmallow inside the bottle. It should fit snugly about halfway down. Now, insert the straw into the bottle, pushing it until it nearly touches the marshmallow.

Here's where the magic happens: take a deep breath and blow hard into the straw. As you force air into the bottle, you'll see the marshmallow begin to compress and deform. When you stop blowing, the marshmallow will return to its original shape.

This happens because the air pressure inside the bottle increases when you blow, squeezing the marshmallow. When you stop, the pressure equalizes, and the marshmallow expands back to its normal size.

Try experimenting with different amounts of air and observe how the marshmallow reacts. You can even challenge your friends to see who can compress the marshmallow the most!

This simple experiment showcases the incredible power of air pressure and how it can affect objects around us.

Suctioned Cup Surprise

With just a cup and a smooth surface, you can create an astonishing display of air pressure's strength.

Press a cup firmly against a smooth surface, like a tabletop or window, and try to pull it straight off. You'll find it's incredibly difficult, as if the cup is suctioned onto the surface. That's because you've forced most of the air out from under the cup, creating a low-pressure area inside. The higher air pressure outside the cup presses against it, holding it tightly to the surface.

To release the cup, you need to let air back underneath it. Try sliding the cup sideways or lifting one edge slightly. You'll hear a satisfying pop as the air rushes back in, equalizing the pressure and allowing you to remove the cup easily.

This simple experiment demonstrates how differences in air pressure can create powerful forces, like the suction you feel when trying to pull the cup directly off the surface. It's a great way to visualize the invisible power of air pressure at work in your everyday environment.

Balloon-Powered Car Race

Ready, set, go! You're in for an exciting race with balloon-powered cars. In this experiment, you'll harness the power of air pressure to propel your vehicle forward.

To build your racer, you'll need a lightweight cardboard base, drinking straws, tape, and a balloon. Here's how to assemble it:

• Cut a rectangular base from the cardboard and attach the drinking straws as axles.
• Secure the wheels (bottle caps or cardboard circles) to the axles.
• Tape the balloon to the straw on the base, ensuring the opening faces the opposite direction of travel.

Inflate the balloon by blowing air into it, but don't tie it off. Instead, pinch the end closed with your fingers.

Place your car on a flat surface, release the balloon, and watch as the escaping air propels your vehicle forward. Experiment with different balloon sizes, car designs, and surfaces to see how these variables affect your car's speed and distance traveled.

Challenge your friends to a balloon-powered car race and discover who can build the fastest or farthest-traveling vehicle!

Egg-in-a-Bottle Trick

Have you ever wondered if you could fit an egg into a narrow-necked bottle without breaking it? With the Egg-in-a-Bottle Trick, you'll see how air pressure can make the seemingly impossible possible.

First, hard-boil an egg and peel off the shell. Next, place a small piece of lit paper into a glass bottle, quickly followed by the egg on top. As the flame consumes the oxygen inside the bottle, the air pressure decreases. The higher air pressure outside the bottle then pushes the egg inside!

To get the egg out, you'll need to increase the air pressure inside the bottle. Tilt the bottle until the egg plugs the opening. Then, blow hard into the bottle; the egg will pop back out.

This trick works because the bottle's mouth is just slightly smaller than the egg, creating an airtight seal. The changing air pressure does the rest.

Amaze your friends and family with this classic experiment that showcases the incredible power of air pressure!

Atmospheric Pressure Crusher

Crushing a can might seem like a feat of strength, but with the power of atmospheric pressure, you can do it without breaking a sweat! Here's what you'll need:

• An empty aluminum can
• A stovetop or hot plate
• Tongs or oven mitts

First, fill the can with about a tablespoon of water. Place the can on the stovetop or hot plate and turn the heat on high. Wait for the water to boil and steam to escape from the opening.

Using the tongs or oven mitts, quickly flip the can upside down into a bowl of cold water. The sudden change in temperature and the lack of air inside the can will cause the atmospheric pressure to crush the can instantly!

This experiment demonstrates how the pressure of the air around us is strong enough to crush an aluminum can when there's a vacuum inside. The boiling water pushes the air out of the can, and when it's quickly cooled, the water vapor condenses, creating a vacuum. The atmospheric pressure then crushes the can from all sides.

Hovercraft at Home

You can create your own mini hovercraft with just a few household items!

You'll need a CD or DVD, a pop-top lid from a plastic bottle, some superglue, and a balloon.

First, apply superglue to the top of the pop-top lid and stick it onto the center of the CD's shiny side. Make sure it's securely attached.

Next, blow up the balloon and twist the neck to keep the air inside. Stretch the neck of the balloon over the pop-top lid, ensuring a tight seal.

Now, place your hovercraft on a smooth, flat surface and untwist the balloon's neck to release the air.

Watch as your hovercraft glides effortlessly across the surface, carried by the thin layer of air escaping from the balloon! The air creates a cushion between the CD and the surface, reducing friction and allowing the hovercraft to move smoothly.

Experiment with different surfaces and balloon sizes to see how they affect your hovercraft's performance.

This simple project demonstrates how air pressure can be harnessed to create a fun and educational toy.

Bernoulli's Floating Ping-Pong Ball

To demonstrate Bernoulli's Principle, you'll need a ping-pong ball, a straw, and some lung power.

Position the straw vertically about an inch away from the ball, and blow a steady stream of air.

You'll see the ball float in the air stream, seeming to defy gravity!

Bernoulli's Principle Explained

Bernoulli's principle blows us away with its stunning demonstration of air pressure in action. When you blow air across the top of a ping-pong ball, you're decreasing the air pressure above it, while the higher air pressure below the ball pushes it upwards, causing it to levitate in the air stream.

This enthralling phenomenon is explained by Bernoulli's principle, which states that:

• As the velocity of a fluid (like air) increases, its pressure decreases.
• When the velocity of a fluid decreases, its pressure increases.
• The total energy in a steadily flowing fluid remains constant along its path.

In this experiment, the fast-moving air above the ball has lower pressure than the slower-moving air below it, creating a pressure difference that lifts the ball.

By tilting the straw slightly, you can even make the ball appear to defy gravity and hover at an angle!

Bernoulli's principle is a fundamental concept in fluid dynamics, with applications ranging from aerodynamics to the design of wind instruments, making it an essential part of understanding the power of air pressure.

Step-by-Step Experiment Instructions

Let's plunge into this enchanting experiment that brings Bernoulli's principle to life!

You'll need a ping-pong ball, a funnel, and your breath. Begin by placing the ping-pong ball inside the funnel's wide end. Now, hold the funnel vertically, with the narrow end pointing down.

Here's the magical part: blow a steady stream of air straight down into the funnel. As you exhale, you'll witness the ping-pong ball defying gravity and floating in midair!

What's happening? By blowing air through the funnel, you're increasing the air's velocity around the ball. Bernoulli's principle states that as air moves faster, its pressure decreases.

The high-speed air you're blowing creates a low-pressure zone around the ball, while the relatively still air underneath it exerts higher pressure. This pressure difference counteracts gravity, pushing the ball upwards and keeping it suspended in the funnel.

Keep blowing steadily, and marvel at the power of air pressure! With this hands-on experiment, you're not just learning about Bernoulli's principle—you're experiencing it firsthand.

Science comes alive when you can see, feel, and interact with its wonders.
