Fun-Flyers, Class Pack, 150 Medium Spheres

By far the best value of all Fun-Flyers, refill packs! The "secret" of electrostatic levitation is in lightweight Mylar shapes. The Class Pack of 150 medium spheres features smaller shapes that can be levitated by any statically charged object - a latex balloon, a PVC pipe, friction rods, or Van de Graaff generator of any size - big or small. An alternative way to detect static charge is to drop a sphere on top of supposedly charged object. The more charge it has, the fuller the sphere expands and the higher it floats. The spheres can be used instead of electroscope to detect the presence of static charge. Perfect for classes, workshops, science or magic shows, great as a construction set to create large, sophisticated flying objects. Medium spheres are indispensable for smaller kids to begin levitating lessons. They are easier to launch and manipulate, and also are harder to destroy as they tangle less. Use medium spheres as building segments to create advanced shapes! Apply only a tiny piece of Scotch tape, as tiny as a grain of rice, to join two segments together. Explore your creativity and understanding of physics by making your own incredible floating structures!
