Science Electrical Invention

Our invention is a tripwire that when someone opens the door the fishing rod wire connected to the cardboard is yanked out of the peg therefore activating the circuit.

Positives
one of the positives is that the circuit works!!!
The circuit is fairly easy to set up


Minuses
You have to reset the circuit after it is activated
This tripwire may use a bit of power


Interesting
i think it is very cool that you can make your own homemade burglar alarm that doesn't cost a fortune.
