Intruder Alert for my Bedroom?

Question

I have sibling that try to get into my room. That annoys me. I want to make a HOMEMADE alarm for my bedroom so when them open my door or walk into my room the alarm will go off and I will hear it all over my house. Can you help? I want to make a EASY one. So easy that anyone can make it.

Thanks,

Kim

Answer 1

Get a great big tin can or two and put them on a shelf - put a thread around them and tie them to the door handle.  Then as the door is opened, it will drag the tin cans off the shelf and they'll make a lot of noise.

Answer 2

Do this fill up a balloon put it in the corner of the door. Then if it is busted then someone came into the room.

Answer 3

In 'Nam, back in the 60's we took tin cans with a few stones in each one, and tied them to the barbed wires out on the perimeter and, when the Cong tried to get through, it of course rattled. saved a lot of lives this way.

Answer 4

close your door then lock it, then place a glass beer bottle upside down on the inside door k**b, you will have to balace it on the k**b.Now when from outside the door k**b is turned the botttle will fall off and let you know that your litle brother is out side trying to get in..If that doesn't work start dating spider man and he can spin a web around your room to keep folks out.
