Rebecca had to build a catapult for her physics class. This is well beyond my abilities and Mark has been working in London. We saved the project for over Thanksgiving where we would have some man-power to build this. Rebecca found the plans and figured out the dimensions ( It had to be under 50cm cubed). She made me a list of supplies. I visited Home Depot. We took everything to Weatherford. Mark and my brother-in-law, Jarom had fun making the catapult. (remember this is Rebecca's physic project). Rebecca put in 4 screws. When she tested the catapult at home, she decided it didn't shoot far enough (4 meters was required). She changed out the bungee cord and painted it silver. The paint made all the difference. lol It shot 9 meters and got at 90%. Go Mark and Jarom !, for a job well done. Rebecca did a fine job of leading the project and her physics grade appreciates the A.
