Picture of Milk Jug Raft
This was a simple, free raft that ended up being surprisingly successful. By now, of course, it is recycled, the jugs gone off to make the next generation of mittens or yo-yos. But it served its purpose as a fun one-day raft on the lake. It took about 30 minutes to construct with on hand materials. I am in the process of building an actual boat, and this was done partly for the practice in instructable-writing, and partly for the fun of it.

There are several other instructables on this site that deal with boats/rafts built from recycled materials, most of which I didn't know about until I posted this instructable. Still, I see no harm in putting this out there.

Step 1: Materials

Picture of Materials
I had been collecting plastic recyclables for weeks, and so I had more than enough milk jugs to make this. A bit of math told me that around 30 jugs would be enough, but this number, like the entire venture, was inexact. In the end I used 34.

Other than than the plastic milk jugs, there were few parts. Two old broomsticks were used as well as one 4 cm wide, 1 meter long length of PVC pipe.

Zip ties were used to hold everything together. In the end I used 25.

Step 2: Prep the Frame

The PVC pipe was roughly split with the saw. A fine-tooth saw blade will work best for cutting the plastic. Be careful when cutting down the middle, as the PVC had a tendency to crack. One of the broomsticks was divided in half as well.

A small (~.7 cm) hole was drilled at each of the ends of the plastic and wooden segments. Zip ties will go through these holes and connect the segments to each other and to the milk jugs.

Step 3: Add the Jugs

This step is as simple as the others, if a bit more time consuming. 34 jugs were attached in pairs to the segments of plastic and wood. Most were loose, but the holes drilled anchored the jugs at each end.

any difficulty paddling??
where do you ride on it? do you just balance on the rods?

The frame held together tightly, so that I could sit on the inflatable ring.
wow. how far out of the water were you? was it just floating right on the surface of the water or did it go in a little?

The jugs went a several cm into the water, and when I jumped on it I got soaked, but other than that it floated out of the water.
