((Just for future reference, traps aren't a one-time use. You throw something in that triggers a trap, it doesn't disarm the trap. When you go in, it'll have already reset itself and be triggered by you too. Throwing items in doesn't make a room safe, it just lets you know it's trapped. Also, some triggers aren't set off by items, such as heat sensors, organic tissue detectors, etc.))
