Little Dipper Mouse Trap

This trap tips when the mouse walks to the end of the plank to eat the bait.  It also automatically resets due to a counterbalance.  A magnet, along with an adjustable bolt, enables the weight required to tip the plank to be fine tuned.  Lean a board against a 5 gallon bucket and add a little peanut butter to the board.  (mice can easily walk on the top edge of the bucket)  Also add a little peanut butter at the start of the plank to build their confidence.  Then put the main bait at the end of the plank.  Adjust the ¼"-20 bolt to trip under the weight of a mouse.  Adjust the counterweight so the trap resets automatically.  Required materials:  ¼-20 steel bolt, #10 steel bolt, #10 nut, #10 washers, ¼" diameter x 1/8" thick magnet, glue.
