Paper Gliders in Perpetual Flight

Description:

The principal is the same as in real aviation: thermals. Thermals allow real sailplanes to fly for hours. As real thermals are to strong for our selfmade paper airplane, we are using a miniature thermal that everyone has in his kitchen: Hotplates. Four hot plates producing hot air which rises and let our paperplane fly as long as we want. The paper aeroplane must be centered while it performs it turns, in the middle of the for heating plates. so it took me about 87 takes to produce this video. if the paper airplane isn´t exactly in the centre of the plates, it will drop off.
