Engineering Activity Pin

This year Thomas picked out a great catapult for the Webelos to build. 

Last year we built the Viking Catapult and was disappointed because I could throw farther then it shot off.  This year we picked out the Roman catapult.  It is made out of PVC pipe.

The Webelos will build it on Tuesday but the Shaw's had to go and have a test run (which was really fun.)  Our friend Ken came along and gave the boys great ideas of what else to catapult other then tennis balls.

 The pictures are basically the same over and over.  You basically have a ball tied to a string at one end and pull down on the other end and then watch the ball fly.  We tried with different lengths of string but were not to successful in getting it to go farther just higher. 

 I guess the best part of the whole thing was listening to the boys tell everyone at church about the catapult and how it dented my car.  Yes, we decided to try a heavy bouncing ball to see if it was different then a tennis ball and we also made the string short.  Well, the ball went way up in the air and then went backwards and dented my car. 

It should be a fun den meeting this Tuesday!!!!!
