Pop n twinbee sfc. Al currently holds the world's record for the longest mousetrap powered car. Rober quickly learns that to have a winning mousetrap car you need a design that will deliver the smallest force over. Mousetrap cars are handy contraptions which teach you a lot about physics and make for a fun project. Find out how to build a mousetrap car and how to make it work for you, in this handy article provided.

When it starts to catch, lift the flap slightly and keep turning until the trap is starting to load. Crazy cake swap install. Keep going until it's pulled all the way back, then hitch it as one normally would setting a mouse trap (see instructions on package I guess). Take a bit of care, because if the string snaps the trap will indeed close (quickly) and anything you have in the way will get hit. It's not exactly deadly, but not pleasant either - these things do pack enough power to make you go 'Ouch'.
