Muggle Materials Experts Draw Inspiration From Magical World of Harry Potter
The best kind of magic is the kind that fires the imagination to use already existing materials in new ways ... and sometimes to invent new materials to answer the challenge.

I really love the idea that there could be a material which is capable of the "really" making the Knight Buss work ... the only question is, would it need nice smooth tarmac roads, or would it be able to tolerate the bumps and potholes of a Venezualean jungle road, or an African dust track without shattering?

Just a thought!
