I had the (perhaps) dumb idea about making paper mache boats after doing some research on paper mache racing shells (http://en.wikipedia.org/wiki/Papier-m%C3%A2ch%C3%A9).
From the first couple of experiments with paper, I found that the material was pretty strong and light, so I made a canoe out of it!
Using several pounds of homework from last semester school, I created a super awesome canoe!
Since it's light, cheap, and flammable (but don't light it)!
Step 1: How the boat works
The canoe is basically super strong paper mache that was shaped by a mold.
I built a mold first and put paper on top.
What you need:
Lots of paper (stuff that soaks up water)
Waterproof glue and flour
Scrap wood (more on what kind on the next step)
Mesh or strips of something flexible
Epoxy, glue, or paint for waterproofing
