Does anyone know how I can create a water sprayer that can be powered by a battery? Answered
Squirrels keep raiding our bird feeders, even though the feeders are in "squirrel proof" cages.
I plan to fit tilt switches to the bird feeders, so that when a squirrel jumps on them the feeders sway and the water gun sprays them.
I just can't figure out how to make the water sprayer. I would like to make as much as possible from scratch, so just buying a water gun would defeat the object.
Any advice would be really appreciated.
