The French Toast starts with the kite on its belly with the nose away from you. A quick jerk on both lines following by a release causes the kite to jump up and invert so that the nose is towards you and the kite is on its back. The lines are resting over the top of the kite. Pull and release both lines again to flip the nose down, away from you, up over itself and then back towards you as the kite resumes the same position, but instead with the lines running down over the trailing edge and under the kite towards you. Keep pulling and releasing to repeat this motion.
This repeated move is generally called a Flic-Flac (or Poisoned Ivy or Cuckoo Clock). By accentuating the "down" beat (that is, when the lines start under the kite) and going easy on the "up" beat (when the lines start on top of the kite), you can create lift. Start with a French Toast and continue with a rising flic-flac and you have a Toast Rack.
