I initially suggest that students study the apparatus more closely, either via a video such as the one at Ref. 6 or ideally with a physical version of the toy. Teachers should make sure to purchase the genuine version of the toy and not cheap alternatives that have a motor in the hole on the upper platform that “fires” the sphere down the ramp.
