Large unstable platform
Climb onto the platform with a few other people. Try to stand so that the platform becomes level. All your moves should be slow and coordinated.
How it works
The location of the centre of gravity determines the position of the platform. If the centre of gravity is in the centre of the platform, the platform is level.
At times a strange-looking system is in equilibrium if the mass is well-distributed. That’s the case, for instance, with the balancing bird available in our shop.
