Pouring Mercury into Liquid Nitrogen (slow motion)
Mercury freezes at -39C ---- Nitrogen boils at -196C More slow mo from periodicvideos: http://bit.ly/chemslomo The three slow motion sequences in this video can be seen in more detail at......

(gas hissing)It's not often thatI think of an experiment for Periodic Videoswhere I really want to know the answer,rather than just having a regular demonstration.Today, I thought of one of those experiements.There is quite a well known effect-known as a fuel-coolant interaction-where a molten metaldrops, say, into water and causes an explosion.And we've sort of had some of thosein some of our videoswith caesium and sodium in water;But there you have a metal which gets hot through a chemical reaction.I had suddenly thought:Why don't we try dropping mercuryinto liquid nitrogenbecause mercury is hot, it's room temperatureliquid nitrogen is at -196° CThe hypothesis is that because the metal conducts heat so well,the heat will come out very...
