IF Men Acted Like Feminists (HATE MAIL SPECIAL!)

So Anita Sarkeesian and Zoe Quinn were both at the United Nations and at Google Ideas this week. Apparently they think that saying 'you suck' to someone online is cyber violence that is comparable to physical violence (seriously... read the report!). Thunderf00t

High speed footage of Potassium explosion
A mixture of footage I've gotten with the new high speed camera. The stuff with NaK reacting under argon is particularly pretty. There is also some explosions of NaK when being dropped on water and some regular potassium tied to a shot glass and dropped into water. The water hammer effect is fantastic. Yeah, this is how depth charges sink ships!

Part of a prelude to a new experiment which is a safe, extremely reliable way of making potassium explode. It so easy to do, and so dramatic that its difficult to believe that this is not going to become a staple demonstration in the class room! :-D
