Forget the colors. How did you use those crystals to travel back in time to the 1970's and acquire that combination of mustache, hair, and clothes?

2:10 that diagram looks interesting. Might make for a good album cover

At 1:58, didn't realise I was listening to Dark Side of The Moon album...

Liquid crystals are a bit more complex. They are molecules that stack, but with a slight angle between each, so they twist like a spiral staircase. When the period of the staircase matches that of a certain frequency of light, that light can pass through the liquid crystal while other frequencies run into the molecule and are absorbed/scattered.

*Who else noticed the smooth transformation of his hair and mustache in this video.* _1:20__, __4:45__, __6:12_




*If you are wondering how, he just used one of his older video to explain **_how hit pipe works._*

I hope you keep the creepy goofy stash. I love your videos and that is a pretty rare look these days. I hope it is your branding. Alway improving my friend, thank you for all you do!
