Fathers with children aged 6-9 are invited to build a motor boat and test it on the water. In this exciting technical master class, children will feel like real engineers, while parents refresh their knowledge and learn something new. Together, they will construct a motor boat using ice cream sticks and a rubber band. The master class is dedicated to the topics of material elasticity and kinetic energy. Participants will develop their engineering skills, technical thinking, and creativity. The finished boat can be launched into the water immediately and tested in action, and then taken home. To attend the master class, you need to arrive on time for the group gathering. It starts 20 minutes before the lesson at the art object "Sphere".
