Insectivorous Fan

This is a fan I built to move the air around my potted plants, which have been supporting a burgeoning population of thrips, whiteflies, aphids, or some other tiny winged pests. Much like some of the larger non-chemical insect traps out there, this moves air through a mesh screen (from a 2.5" diameter mesh tea ball) that traps the insects in a breeze they can't fly free from. Then, if they stay there long enough, they die.
The bottom base pops off to allow you to empty the fan of their little carcasses. If you want to hasten them along, you can add water or some scented oil that they can drown in.
I ran the first version overnight and it trapped about fifty of the little suckers.

It also makes a nice desk fan; the exit spout is orientable, so you can direct the breeze away from the intake, and it has a fun form that looks nice on a desk. I printed this one in red but I plan to make the ones for my windowsills in green so it blends into the foliage better.
