Hey guys... I got this zip and i'm trying to split it into 8ths, grams, and a quarter... I don't have a scale, and we're just trying to figure out if anyone knows how to make a scale. I'm pretty sure i can make a simple balancing scale, but I don't know what kind of every day objects weigh a gram... I've heard a U.S. Currency quarter weighs a gram but i don't know if this is true, can you guys help me out?
