If you want to leave Earth, you have to combat a great force - gravity. Powerful rocket motors have sufficient performance to defeat gravity. We try out how the forces of such large rockets work to propel them into the air on small, home-made water rockets.Accompanying persons do not need a ticket unless they wish to actively participate in the workshop.Please bring an emptied and rinsed 1.5-litre PET deposit bottle  along with you, which you can convert into a functioning water rocket following our instructions. (The bottle should be round and have a bottle opening diameter of 2.15 cm.)We then test how far the resulting models can fly in a flying competition!Image © SPB, Foto: Pedro Becerra
