A few years ago I was inspired by a very short video of a man making a small boat from recycled bottles. No matter where I looked, I couldn't come up with any instructions on how to make one of my own, so I had to set out without much guidance. I decided it would make a great dorm project because it was odd, messy, and yet totally inoffensive.
This is a really entertaining way of reclaiming and recycling those pesky plastic beverage bottles that always seem to be lying around, and it always turns a few heads on the lake. As an added bonus, it's recyclable!
The boat I've made resembles an open-topped kayak. It measures approximately 3 x 7.5 feet, and weighs roughly 50 lbs. Because the lids of the bottles are twisted on tightly, they keep the thing afloat, even if it’s swamped with water, so it’s basically self-bailing! It's perfect for flat water, and surprisingly durable, but I wouldn't advise anyone to try even small rapids with it.
You will need just 3 things:
Plastic bottles with lids tightly in place (about 270). I used 20 oz. sports drink bottles because of their size and durable construction.
Adhesive. I used Liquid Nails polyurethane adhesive. I tried to use silicon caulking, but it just wasn't sticky enough for me. I'm sure there are better options.
