About Project

Electric human centrifuge game, battle your opponent to see who can handle the most G-force.  Tops over 5G! Constructed for “Red Bull Creation” national engineering competition 2012.

How to play: Both players press and hold their button.  Spinning commences, and G-force builds until someone can’t handle the forces.  The person who holds their button the longest wins; the first to let go ends the game.

Total build time:
72 hours
