Flying object propels itself by flipping inside out
The design is based on the inverted cube shape discovered by inventor and mathematician Paul Schatz. By dissecting a cube into three parts, two star-shaped units can be produced at either end with an invertible belt in the middle section which is the same shape as the flying band. The system reproduces the entire structure: it opens to release the band while the ends remain on the ground as a docking station.
The video seems odd, though — it looks like they speed it up in spots, making it more difficult to tell what’s actually going on.
