Fun Fact Friday! For the upcoming GBC 55 Spring Launcher we worked together with Jorian Doornenbal from the Netherlands. This GBC is made from the LEGO 42139 All-Terrain Vehicle set which has so many useful parts! So we had to choose on what would work and decided on a shooting mechanism that could use the 6 springs that come in the box. Managing that many forces created by the springs brought us a new challenge. How to load them without breaking your LEGO! We could of course use fewer springs but what is the fun in that? Using the black curved beams we are able to slowly load the 6 spring mechanism, building up energy and releasing it all at once.
