This has got to be the prettiest demonstration of centripetal force and inertia we've ever seen! This cheerful iridescent device reflects a dazzling rainbow as it spins. Twirl the stick and watch 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! Since 1992 Kikkerland Design has established itself as one of the top companies in the world offering unique, inspiring, well-designed products. Love cool stuff?
