Try out the assembled catapult, measure its basic physical characteristisc and work on further improvements. Share your suggestions with project partners, comment and improve. Organize a competition for the most powerful catapult and logo of the project. Navrhnout s pomocí ICT vymodelovat, pomocí 3D tiskárny vytisknout a sestavit středověký katapult. Konstrukce může být libovolná s využitím sil pružnosti v tahu, kruti či ohybu.
