Call IN when the kites are lined up and stationary. The kites are 'floating' at ^10, with the centres of the kites about one kite-width apart. Kite 1 starts rotating 180° clockwise. When the kite has rotated 90° Kite 2 starts rotating anticlockwise. The following kites turn in the same way, alternating clockwise and anticlockwise. Call OUT when the last kite has turned the full 180°, with all kites still at the same height.
