There are 6 different body parts, 2 legs, 2 arms, a torso and head. When you stick the body parts on to the electromagnets it plays a different audio program for each part. When all six parts on it starts a program and the body falls to the floor, one body part at a time. That creates a dry contact that could trigger things such as a book case doorway opening, a black light shining on a secret clue, and audio clue etc. For an escape room you might hide all the body parts and have the group find them placing them on one at a time. Then when all on it could trigger another clue or a way to escape. Comes with audio and lights. AC power required.
