42m Balloon Jump Challenge

The last one was 36m Shipping Canal Budget Build Challenge!

I Think we should have weekly challenges in on here. So the next one can start tomorrow.



Any one have ideas for the challenge. It can be different ones as well like shortest or with the lowest stress or it most be this type of bridge.



In the last challenge a lot of people me included created a over pass instead of a draw bridge because they are cheaper to make.
