Why doesn’t anything stick to Teflon? [Science Video]

Teflon was in the spacesuits the Apollo crew wore for the moon landing, in pipes and valves used in the Manhattan project, and it may be in your kitchen, as the nonstick coating on frying pans and cookie sheets. So what is this slippery solid — and why doesn’t anything stick to it? Ashwini Bharathula describes the science behind Teflon.

30 Great Video Game Themes Played on Bass

You may not think you appreciate bass guitar, but after you watch this dude nail 30 video game themes on his bass, you might find yourself respecting it a whole lot more.

I suggest playing it with eyes closed first and seeing if you can GUESS the game score, and then watch again to see if you are right (as he lists all the names of the games he is playing the themes from).

Very cool.

Did you know: Shark are attracted to the sound of death metal because the music mimics the “low frequencies of struggling fish.”

The team trades chum for music, hoping to strike a chord with nearby great whites. Luckily (or not), great whites have an ear for death metal.
