A movie that strikes humans towards the sky

Why do humans want to fly this way? Try squatting people who sat while sleeping like a sling shot, flying in reverse bungee, flying with catapult, gathering movies flying in various ways Saw.

The playback of the movie is from the following. People sleeping on the chair at the poolside (?) Are flying. There is no such thing as a splash of splendor. It's fun to truly skip it, but it's fun.

It is similar to the so-called "reverse bungee". It is launched high in the sky and descends from there with a parachute. You look feels good.

It seems to be a CM that tightens the seat belt. The smile full of sight when sitting catapult is wonderful.
