this is the lowest costing mouse trap you could possiblly make. it doesnt hurt if it snaps on you.
what you need:
a minimum of 3 rubberbands
an altoids tin
Step 1: Making It
this is the easiest thing you counld make on instructables.
put the rubberbands around the CLOSED altoids tin. put them equaily apart. open the tin
Step 2: The Trickiest Part
open the tin. push the lid down past its point a little bit. it will be a bit trick to get set. once its done, it should stay open untill...
P.S. dont forget to put food in it...
Step 3: SNAP!!!!
when something goes to get the food, it has to mess with the rubberbands. this sets of the trap.
