I remember this being on Tomorrows World (which is a show that needs to come back), and practically every year that memory pops into my head and I wonder whatever happened to it. I think the segment ended with him showing it to NASA. If I remember correctly, he created it in his garden shed using off the shelf products that you could buy on the high street, and he just started mixing them together and testing the results... and I think hairspray was mentioned as being an important ingredient. Or maybe my mind is full of holes.
