Luanga Nuwame is a cardboard craftsman. He can make just about anything out of cardboard, including a Groot, a sundial, and a rocking chair.
Nuwame's latest challenge is his most demanding. He built an articulated elliptical trainer workout machine using nothing but cardboard and glue. It can move and support his weight. He used 9 layers of double corrugated cardboard as material. But even that wouldn't be enough to hold his weight if he hadn't designed the balance perfectly. Nuwame writes:
Cardboard can only take so much downward pressure and uniform balance is the key. Once on and balance is kept, the machine performs as designed. There are still more improvements to be made, but at least I can say that, “YES, it is possible to make a functioning elliptical out of cardboard!” (…not like anyone was asking)
