I just drew this up real quickly..... seems like a good plan!
1. mouse climbs up box
2. mouse reaches for cheese
3. pulls lever
4. ball rolls down ramp
5. scissors cut string
6. spring opens trap door
7. snake eats mouse
8. upload video to youtube!!!
Odds are the mouse would get startled from the dropping ball and take off before the trap door opens. Mice arnt known for being brave.
Most effective mass mouse trap I've seen is a five gallon bucket filled a quarter up with water with a wooden doweling suspended in the middle by a
nail on each end. Put peanut butter in the middle of the dowel and spray the whole thing with Pam. If you have a cabin or lodge or camp site this
sucker will kill mice 24/7 I've seen 20+ mice caught overnight before. Sure it's a bit cruel because the the little suckers swim till they sink but
it's war!...war never changes....
