In my high school chemistry class, the teacher showed us sodium in water 
- small sample, so it just fizzed and shot around the tank a bit.

The teacher in the next classroom (which shared a storeroom with our 
classroom), though, was not thought of as being the brightest bulb in the 
package; he took a piece that was significantly larger and dropped it in 
for his class.  It exploded with a very loud "bang", and there was 
smoke...

Friend of mine was in the class when he did that.
