The Hot Wheels® STEAM Balance Shift™ Play set helps kids understand the science of equilibrium through fun, competitive play as they use the slam launcher to send their cars up and over a seesaw to secure the trophy. Force and speed are the keys to victory, but the real winner will gain a better understanding of balance and gravity while having fun. The set comes with one Hot Wheels® vehicle, but it includes two launchers for side-by-side challenges (additional cars sold separately). Designated slots hold cars, track pieces and launchers for easy and convenient storage. Colours and decorations may vary.
