We love coming across projects that when you first hear what they are all about you say, 'surely that can't be done'. This is exactly what we thought when we heard about Izhar Gafni's Cardboard Bicycle Project.
Drawing inspiration from a cardboard canoe (yeah we're with you: HOW DOES THAT WORK?? Cardboard + water = disaster right?), Izhar made a cardboard bike from scratch using origami techniques. It is capable of sustaining up to 485 pounds, that's over 200 kilos!
And the best thing: it only cost about $9 or £5.50 to make!!
Take a look at the making of in this video:
