We found out it was not so easy to make the car move! A great deal of tweaking was required! This is all part of the design cycle and you have to be prepared to spend time making adjustments!
I heard lots of great advice today :
" The body is too close to the ground, you need to adjust the axles."
" The axles should be under the car body , not on top."
"The balloon is too heavy and causes drag...try a smaller balloon."
" The balloon is in the wrong position ... it is too near the end of the car."
" The wheels need to be on the ground"
At home you need to tweak your car and test it and tweak it until you are satisfied with it! Good luck! You can do it!
