Hackers are innovators. Hackers are people who challenge and change the system to make them work differently—make them work better. It’s just how they think. It’s a mindset. I’m growing up in a world that needs more people with the hacker mindset, and not just for technology. Everything is up for being hacked.
13-year-old hackmaster Logan LaPlante discusses how “hackschooling” — taking a hackers’ approach to education — helps him to take full control of his education in his TEDxUniversityofNevada talk, "Hackschooling Makes Me Happy."

Don’t try this at home: TEDxTempleU speaker Mike Zdilla pours up a liquid nitrogen cocktail to demonstrate the Leidenfrost effect, a phenomenon that occurs when a liquid comes into contact with a surface that is much hotter than the liquid’s boiling point: in this case, liquid nitrogen and Professor Zdilla’s mouth.

Says Zdilla in his talk:

My tongue, as far as the liquid nitrogen is concerned, is incredibly hot. So as soon as it comes close — before it even touches me — it effectively is instantly vaporized into this barrier gas that protects me from the liquid nitrogen … So the liquid nitrogen doesn’t ever really actually touch my tongue. 

Zdilla first tried this wild vapor-breathing as a way to explain the chemistry behind harnessing renewable energy sources — such as hydroelectric, wind, geothermal, and solar — and look for ways to make them work for us. Here’s what he discovered:
