Actually the fourth he threw was francium (I think). But he used a very small quantity, and the result is not appreciable ^_^

He's throwing alkali metals into the pond to make them react with water.

I wish I could have gone to a good university like that instead of FSU.

gee aren't you a fun person

[JBnotthescotch]

@NoPetrol yeah...

excellent vid!

[panteraboosh]

Caltech or berkeley?

@DJDorianGray If you listen carefully to the video, he clearly says Cesium, but due to the way in which it reacts with a liquid and the fact that it is rather expensive, he only used a very small quantity.

Thanks for uploading!

@DJDorianGray There is no way that was francium. Francium is extremely rare and extremely explosive. It is thought that about 20-30g (1 ounce) exists at any given time in earth's crust. What is much more likely is that it was rubidium, which is the fourth element in the alkali family.

I went to Caltech for a marine bio camp. I was ( and am) 12. It's an awesome school. =P The main thing I remembered was .. The turtles.

such good memory of freshman year at caltech.

[appa609]

no, francium is so radioactive that it can't exist for any meaningful period of time.

My daughter is freshman at Cal Tech and said this years demo was even more awesome!
