Tales from the Prep Room: Magnus Cups
Produced by the Royal Institution, this video demonstrates the effects of air movement over a spinning surface and how it can be used to generate lift. The demonstration is simple and uses just two polystyrene cups joined to produce a 'Magnus Cup.'
When launched, the Magnus Cup spins backwards and this generates lift to support some of the weight of the cups as they fly downwards. A similar effect is seen as the path of a tennis ball or football curves through the air, when a player applies a spin to the ball.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
