RND BBQ special: Water balloon launcher!

In preparation for the up-and-coming RND BBQ, we tested our first water balloon launcher design. 

It was super simple, only cost $15 and threw a water water balloon over 50m! with some simple mods it should have fairly repeatable accuracy but that’s for others to figure out, I’m going to test a different design… :)
Now we just need a castle made out of tissue paper…
