Make a STEM Connection!
Let’s work together to inspire the next generation of scientists and engineers. At Steve Spangler Science, STEM is not just an acronym or a checklist of required subjects (science, technology, engineering, and math). Our STEM products encourage young scientists to create new and exciting experiences that foster the skills of collaboration, communication, critical thinking, and creativity.
Amaze everyone by blowing up a Windbag with just 1 breath!
How many breaths does it take to inflate an 2 m (8 ft) Windbag? 70 breaths, maybe? Why even try? With a simple science secret, you can amaze your friends by blowing up your Windbag in one breath! Windbags are so light and strong that even the smallest scientist can demonstrate the amazing properties of air!
Discover the Power of Air
Let’s take this Bernoulli’s Principle out for a spin and see what else you can do. All you need is the small funnel and ball found in your kit.
Build 3D Geometric Shapes By Joining Several Windbags Together
Hook two rubber bands together by laying them on top of each other and pulling them through each other in opposite directions. Use the rubber bands (not included) to arrange the tubes in various shapes. Make giant cubes, triangles, pyramids, or even giant balloon animals.
