| 説明 | My father's bird feeder has been under siege by squirrels for years now. After they smashed one by gnawing through the rope it hung from and then chewing through the plexi of the other feeder - he took the defenses up a notch. Utilizing his electrical engineering skills he wired a low voltage deterrent designed to leave the birds un-shocked - but with multiple contact plates that shock the squirrels. The birds only touch one at a time while the squirrels typically touch two completing the circuit. Alas some squirrels are too damn hard to give up. |
