Technology bp challenge

Last Friday I went to the gym to do the bp technology challenge. There were 4 other kids in my class who were also coming we were a group of 5. In my group there were Matt.S, Milly, Jessica.C, and Britney. For the first challenge we had to make a structure out of drinking straws to hold a marble attached to a string. Then the second challenge we had to make a parachute for an egg to fall from a hight without cracking. Finally we had the last challenge I can't remember what we did but I'm sure it was fun.
