Andreas, you really SHOULD be careful mixing unknown chemicals! I'd also be leery of taking pics like this at work! I would think there are other Technicians/personnel there and they would wonder what you're up to! Also, if there are security cameras, (like many facilities have), you may have been caught on tape! (I certainly hope not!) Anyways the bottles in 1 & 2 are called a "flask" as Doug mentioned. Cool drop shots...hopefully worth the risk you took!
