this afternoon my group, honore, clara and i tried to launch a balloon up a string to the wall. the first test we taped a balloon to a straw, but we taped it to far down. so the next test we taped it on the middle of the balloon and it went up. i did this test in the 4th grade so i tried to use what i remembered from then to get the balloon up. next we taped a wheel to the balloon but it was to heavy so we used four. it didn't go up because we pinched the balloons to tight and the didn't open. i wonder what would of happened if we had used more balloons because if we had more air force it would minamize the gravity and it might of carried the wheel.over all i think we did pretty good :)
