Eureka Lab video maker

A question on top, a glowing little experiment that answers it, and the answer in yellow at the end. Nine experiments: mirrors that catch every ball, chain reactions that run out and back, orbits that draw a flower, rings that line up again, bounces that draw a star and an edge that never ends. Each has six layouts, eight scenes and its own sound.
