I need help (school project)

[Frogger]

Thanks for your help guys. I was able to get it to go like 7 feet. Only thing is that it doesn't have to look like a frog. So, I used an index card and folded in half a few times to make it thick. Then I just folded it over and over to kind of make a "spring". (4 folds) Thanks for you help and advice. Hopefully it works on my 1st try.(2 tries)
