I have to dig up the rules sheet on this one. The constraints made this contest awesome. If memory serves, the constraints were:
No electricity
Device had to be, at most, 4'x4'x'4 in size
There were two contests:
1) Longest "drive"
2) "Closest to the pin" at 150yrds
Out of the gate, Brett shows his sneaky detachable air pump arm system to charge his air cannon. Ugh
..me in disbelief
Admiring the facial mockery I attached to my garage door spring powered device
Jason's geared up, spring-powered club
Nick's massive slingshot
...the ladies lamenting their marital choices...
...and a few shots with a bad iso setting
Ryan goes for longest drive the legit way
Earlier prototypes
