The prettiest demonstration of centripetal force and inertia we've ever seen! This perky, iridescent device reflects a dazzling rainbow as it spins. Twirl the stick and the thin ribbons spread into a bubble shape. The faster you spin, the wider the bubble becomes! It can be gently twisted by hand to make a delicate 'flower' that neatly tucks itself into a tight ball. Endlessly fascinating! Available at teachersource.com/product/mylar-wand/physics
