Catapult vs Tribuchet

Its really fun being a handyman dad during the science fair. Yes even though Jacob is only in first grade, at this charter school he to must participate with a science project or a model. He wanted to do a model of a catapult.


So we went to the best video authority I could think of for catapult's - the 3rd movie out of ht eLord of the Rings Trilogy, Return of the King. Not only did Jacobget to see catapults in action but he also got to see trebuchets - which really got his atention. This last weekend we bulit one and he learned so many lessons: leverage, counterweights, saftey, and triangulation - not to mention the importance of planning and assembling things methodically.


The best part is on Monday we got to use is and launched over 10 ballons until it broke. Check out these pictures!
