Chest Traps
Chest Traps create deadly lingering potion clouds when a container with a Chest Trap in the first slot is opened. They come in 5 flavors - one of which damages you directly.

5 - Run away (or don't)
6 - Come back 3 seconds later -- the cloud will have faded away.
7 - Open the container and notice that the Chest Trap has become a harmless, Empty Chest Trap.
8 - (Optional) Refill your Chest Trap with a good old
