This is what you need. You need a flip flap*. I recall you saying you were amazing at killing plants. Well guess what, me too. This is my new toy, and I bet I can't kill it.
It's solar powered and just sits there wiggling away happily as long as there's enough light for it to pick up.
I urge you go out and get one Cal. If you can kill that, I'd be astonished!
*I did not pay $49 dollars for mine.
