I got the idea for a cardboard boat from the many photographs and videos on the web of cardboard boat races. But while many of those boats are designed to stay afloat for a few hundred yards, I wanted to make one that would be durable enough to last a few years. So I took some ideas from the internet along with some ideas of my own, and made a single-person cardboard kayak. It’s been several years and it still floats. I’ve made videos of the boat in action on Meadow Grounds Lake, the Juniata River, and the Potomac river. I wrote a blog post about the construction that includes some frequently asked questions and a video explaining the construction. I also have a YouTube playlist that contains several videos of the boat, from construction to fishing out of it.
I’ve made solar ovens out of anything from cardboard boxes to old satellite dishes. In the case of the latter, I have recorded a video of the construction. And they can cook just about anything. Probably the easiest solar oven to make is one based on the CooKit design. I recently made a video of me cooking a whole chicken using that solar oven. My other solar cooking videos are below:
This little craft makes use of an old CD or DVD, a Styrofoam egg, and a couple of golf tees. This video explains the construction process, and this blog post will give you details and a materials list.
You might want to resist the urge to throw these things like a Frisbee, though, because the edges can be a little sharp. A better idea is to use fishing line to attach them to the ceiling for decoration.
Like many of the others, this idea wasn’t original with me. I found a picture of soda bottle broom on the Internet, but the instructions were vague, so I made one and recorded a video of the process as well.
Do you know of any other cool recycling projects? If so, put your ideas on the comments below.
