Although this is probably not a project many of you are jumping to recreate, I did think you would find it interesting to see how strong a few little pieces of cardboard can be.
Electra has been wheeling around on her tricycle these days, and is keen on making her bike into more of a workhorse around the house. We have a wooden plant coaster that we have also been using as a kind of wheelie body board that makes a perfect trailer. We just needed some kind of hitch so that Electra could easily take off the trailer when she was simply "cruising."
I measured and sketched, and then cut out this little device made of three pieces of cardboard glued together. It's surprisingly strong- it's able to pull a lot of weight (at least 10 kilos) without looking stressed. The trailer hooks up with some braided paper cord, which I used to illustrate the power of paper! I love continuing to be surprised by cardboard. It's free, recycled, and recyclable and offers so much possibility. I just find it so darn cool! What do you do with your cardboard?
