The Spring Introduction Programme 2015 welcomes 186 international students who follow an obligatory programme. Throughout a week of project work students design a water rocket, get familiarized with the Delft study method, and working in multicultural groups.
In all, about 5 prototypes were considered by the design team, successive designs attempted to build upon one another to achieve the final product. The first design involved cutting bottle C in half and connecting it, tip facing away, to bottle R. The following designs tried various shapes of crowns. Then rubber bands, tapes and clays were tried in order to make the rocket more stable. Finally, a long rocket with wings and two parachutes was chosen and it works well!
