The RedBull (Opposite to) Custard Wing!!
Maybe it’s a weave of carbon fibre that act’s the oppisite of custard!
Custard is solid when high force acts upon it, punch it and you can’t break the surcface.
However when a low force is used it acts differently, slowly put you’re finger in a bowl of custard, and it will go through the surface of the custard!
At low speeds/standing still, where low forces are put on the wing, it is solid and immovable.
So maybe the high forces at high speed, acting on the wing cause the properties of it and make it bend!
April 1st – I’m sure you’ll hear more far-out things today than my theory.
