This challenge is very efficient to get people that do not know each other to work together. The aim is to compete as a team in building the highest tower that will hold a smartphone as vertically as possible. There are strict constraints : time is limited and they’re only allowed to use certain materials. At the end, the height at which the smartphone is standing is measured but a penalty is applied for each degree out of verticality.

Here is all you will need to try it for yourself !
