Instructions:
1. Human Bridge: Players must hold hands and simultaneously touch two metal contacts to trigger the 12V electromagnetic lock to open. (The contacts must be connected to a large metal object to increase the contact area.)
2. Watering: Simply place the two metal contacts in a container such as a cup or vase, then pour water to create a conductive connection between the contacts. This will trigger the 12V electromagnetic lock to open. Reset: Release the hands, drain the water, power on, or wait one minute after triggering to reset.
