Equilibrium platform

HOW

1. A few people are needed for this experiment.
2. Climb the platform together.
3. Try to position yourself so that the platform is horizontal.
4. Any changes in your position should take place slowly and in a coordinated manner.

WHY

The position of the platform depends on the location of the centre of gravity of the entire system. If it is in the centre of the platform, it adopts a horizontal position.
