Yikes, someone made a real “Fly Plane“. Not every cute illustration should end up “real” – Spatula writes -

After coming across this lovely image depicting the construction of a fly powered matchstick airplane, I had to try it for myself. Here are the flies, trapped within their impenetrable polyethylene terephthalate dungeon of doom. As difficult as it may be, avoid pouring the hydrochloric acid in with them. They find it very unpleasant, and may refuse to fly for you. Wait until after you get bored with the plane before you decide to bathe them.
