How to make an efficient and free intrusion alarm
If you want to know if someone is trying to get in using the door, this is a very easy to make alarm for your home or hotel room. Just take a mug with a handle, or something similar, and fill it with silverware or other metal objects. Hang it on the inside of the door handle. When someone, like a burglar or curfew-breaking teenager, pushes the handle, the mug and silverware will fall to the floor making a terrible noise.
