Because Lego…end of story! Seriously, anything epic that can be made using Lego suddenly becomes so much more epic that it needs its own epic scale. There are tons of examples of Lego pipes on bongs on the web, but to be perfectly honest there’s no beating the classic, simple designs like this. Retro, easy to make and a doddle to destroy and hide the evidence if you’re caught out. Plus there’s the option of building yourself a nice little house or racing car, if you find yourself going through a drought and need to kill some time before your next delivery of bud arrives!
