Some of my friends are torn between the absolute cool things i make with paper and the uncool fact that i am crafting with paper; but I am super cool with that because i like my hobby! THIS guy in the following video clearly like paper too! Youtuber Aliaksei Zholner crafted a fully working badass V8 engine out of paper! Ok, he cleary said that he used some scotch tape ” on valves to eliminate friction” but i think this is completely ok! And if this would not be cool engough: It works with compressed air from a balloon. Freakin awesome! Go and check his Video out!
