Amazing Marshmallows
Institute of PhysicsAdd to list DetailsIn this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle. The marshmallows will...
Tired Weight
The ExploratoriumAdd to list DetailsYes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and...
One In The Hand
Institute of PhysicsAdd to list DetailsIn this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge. Use this...
Ping Pong Ball Shooter
MakeAdd to list DetailsIn this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine. This model utilizes Bernoulli's principle to create an area of low air pressure so that ping...
Jam Jar Jet
MakeAdd to list DetailsIn this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust. Learners will be...
It's a Gas!
Oregon Museum of Science and IndustryAdd to list DetailsIn this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing. They combine...
Balloon in a Flask
Oregon Museum of Science and IndustryAdd to list DetailsLearners observe a flask with a balloon attached over the mouth and inverted inside the flask. This display from The Nature of Matter unit in OMSI's Chemistry Lab has great potential as a...
Cartesian Diver
Institute of PhysicsAdd to list DetailsIn this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water. This...
