it uses a bamboo prod/bow
it can fire about 30ft
it will go into a wooden plank easily
it is very fun for target practice

for the rest : normal hardwood (but any will work)
also i dont think plywood would work
ps. thanks for all the feedback
its nice to have helped :)
Just look at the pics and make your own from the ideas
The bow is a split piece of bamboo
The trigger is a right angle chunk of board that pushes the string off of the notch
Thats about it
the bow is held on with normal string but I had to tape around the bamboo to stop it from breaking
