Fly

Last week I had some students writing recipes for me. One student didn't finish hers, and gave it to me today at the beginning of class. It was even printed, very unusual here, where most students don't have a computer. I skimmed through it, and the following instruction caught my eye:

Dissolve the egg, and fly.

I decided to bring the recipe home to try, but I can't figure out how to dissolve the egg. I'm working on it, though. Flying is next.
