With the Wind Bag Chemistry and Physics Demonstration, students will be blown away by your amazing lung power! The wind bag is an 8-foot plastic tube which, with a little practice, can be blown up with just one breath!

## Product Details

Students will be blown away by your amazing lung power. The wind bag is an 8-foot plastic tube, which, with a little practice, can be blown up with one breath. It demonstrates Bernoulli’s principle and how air pressure changes help you blow up the bag. Made of durable plastic, this bag can also be used as an air lift. Elevate heavy objects by blowing up wind bags. These bags help explain some amazing, yet difficult-to-teach concepts.

MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object
HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
