![]() The Mythbusters built a balloon that was roughly a cube shape, with each side measuring 3 meters. This myth was actually tested on Mythbusters once, and they determined that yes, a balloon made out of very thin lead foil can float when filled with helium, provided it's big enough. There's a myth that a balloon made out of lead can't float. Plus, the 30 best science websites for grades K-12.Real World Physics Problems Newsletter - Lead Balloons, Issue #30 May 02, 2016 Have more balloon experiments to add to the list? Come and share in our WeAreTeachers HELPLINE group on Facebook. Experiment with balloons and push pins.Ī pin pops a balloon in no time flat, so what happens when you place a balloon on a table full of them? Once again, the answer won’t be quite what your students expect until you explain the science of distributed pressure. Fireproof a balloon.Ī balloon will obviously pop when touched to a hot flame, right? Not if you put some cold water in it first! Kids will be so amazed they won’t even realize they’re learning about the heat conductivity of water. Watch the balloon expand and contract as the air around it changes temperature. That’s where this experiment comes in to save the day. The concept of expansion and contraction of air can be hard to visualize. You’ll only need simple supplies like a plastic bottle, straw, and putty. See the power of air pressure when you build a balloon-activated water fountain. To really understand how it works, use some incense to create visible smoke rings that will really impress your students. Fire up an air canon.ĭiscover the power of an air vortex with this easy DIY air cannon. They’ll want to try other objects too, so hold a contest to see which spins the longest. In this simple experiment, students use kinetic energy and centripetal force to spin a penny inside a balloon. The next step is to hold the balloon over a compact fluorescent lightbulb (CFL) to see it glow from the static electricity. One of the first balloon experiments most kids try is rubbing a balloon on their hair to make it stand on end. ![]() Power a light bulb with static electricity.

You have two balloons, one filled with more air than than the other. Sink or swim with water balloons.įill water balloons with a variety of different liquids like oil, salt water, and corn syrup, then float them in a bucket of water to learn about density and buoyancy. Water balloon experiments make a big splash with kids! In this one, they’ll explore how air resistance slows a water balloon’s landing using a homemade parachute. An old CD and a balloon help demonstrate air pressure and friction in this simple experiment. It’s not exactly the same model the military uses, but this simple hovercraft is a lot easier to build. This experiment uses balloons to model a two-stage rocket launch, teaching kids about the laws of motion. The rockets used for space flight generally have more than one stage to give them the extra boost they need. Learn more: Surviving a Teacher’s Salary 9. This clever model helps explain the process. Instead, the contraction of the diaphragm pulls air in and forces it out. Your students might be surprised to learn that lungs have no muscles to make them work.

Assemble a heart pump model.Īnatomy lessons literally come alive when you do balloon experiments like this one. Just how do fish manage to float without sinking or rising? Find out when you explore buoyancy with this swim bladder experiment using a glass bottle, balloon, and a few other basic materials. ( Get more science experiments involving ice and snow here.) Kids learn about crystallization and the expansion of water as it freezes. The next day, carefully cut open the balloons to reveal the beauty inside. Create ice crystal explosions.įill balloons with water and leave them to freeze overnight. Take this one outside on a sunny day and let kids splash away while they learn! Float a balloon-powered boat.ĭiscover the power of air pressure and the third law of motion with this fun and inexpensive balloon experiment. If you do this one right, you’ll make kids’ eyes pop-but not the balloon! They’ll learn about the polymers that make balloons possible, and even a little bit about how to stay cool under pressure.
