For the challenge today I give you a problem that has you refelct on a design for upgrades and modularity. The problem is building a juggling machine; first to operate in a vaccum and then to operate in an open field. Also you must go from juggling rubber balls to eggs to knives. I hope you enjoy the show. If you would like to interact with Soap Box Rocket, then follow Craig on twitter @SoapBoxRocket.
