So, me and a friend started playing a LOT of music, we are also command users (not cheating technically as its our world, our rules.) so we would like to have the ID's for the various instruments that are added from FU. And then I just want a bunch of liquid metallic hydrogen because I want to actually research everything (to say I have) plus I want to mess around with it, but I dont know how to get it, where to get it, etc. Please help!
