OK, bare with me here. I think it will be worth it.
If people dare to discuss conspiracy theories others will often brush it off by telling them to go put on their tinfoil hat. However, the science behind why one would wear a tinfoil hat is sound. Aluminum is a non-conductive metal. So, if you were trying to protect yourself from electricity or some sort of directed energy beam it would be a good choice of material to use. Then I thought about the Tommy Copper knee brace I sometimes use that is, apparently, infused with copper throughout the fabric. Well, if that's possible then surely an aluminum infused hat of some sort should be possible. It would just look like a normal hat but only you would know it's actually tinfoil. Think of the commercial possibilities of such an item. If I had the time, inclination and energy to do it I might try myself but I'm too busy with other things lately. Someone should do this though. I want my fashionable tinfoil toque!
