Soapbox Racers: Energy science that actually moves.
Pull back your racer, let go, and watch it zoom - powered by nothing but a rubber band and the science of stored energy. Fold and assemble a flat-pack cardboard racer, rig up the rubber-band launcher, then customise it with mix-and-match themed carts and drivers.
Every centimetre of stretch loads potential energy; the moment of release converts it into kinetic energy - pure speed, no engine. It's a simple build with a genuinely satisfying payoff, and a clear, physical way to understand energy, elasticity, and the relationship between stretch and speed.
Ages: 5-12 (ages 5-7 may need a hand with assembly) Mess level: Low
