Solid Sodium Thrown Into The River
Grade nine science teacher did that on a much smaller scale in the classroom. He had one reaction get away from him that left a big black stain on the ceiling tiles. And then they made him superintendant of schools.
But… but… explosions!
What he said.
Grade eleven chemistry teacher for me. Small piece of Na, but the school had these massive lead sinks in the lab (almost a century in age), so when it exploded it made a loud bang, but no real damage. i think a chunk of elemental Lithium was next. It did a lot of fizzing and bubbling, but no explosion. It was a lesson that made that end of the periodic table stick in our minds. Old beaky could be a lot of fun.
Damn, science is scary!
Sodium, a highly reactive metal, and Chlorine, a poisonous gas, combine to make …
Don’t be cruet
If you really are interested in inorganic chemistry (or even if you are not!) then try searching for the Perodic Table of Videos produced by a genuine professor of chemistry (Professor Sir Martyn Poliakoff) who really does look like a mad professor!
On the home page, spot the mad professor (hint, he’s in red with a huge white afro-style hairdo).
(This is genuine. Produced by the University of Nottingham, in the West Midlands of England. There is a video for each of the 118 elements plus many other interesting bits and pieces. For a picture of him being executed, sorry, knighted, by Prince Charles see http://universitybusiness.co.uk/Article/famed-chemistry-professor-awarded-knighthood

Back when Britain cared about foreign invaders and were short on weapons they took milk bottle and filled when with phosphorous and oil (to keep the air away from the phosphorous). You could throw these at foreign invaders to make them think twice about their actions. To this day crates of these things routinely turn up in barns, basements and attics.
In the 70s they build a nuclear reactor on the Dutch German border, they used sodium in the primary cooling loop and water in the secondary. It was never started up because some events during testing. Sodium and water in one system, what could possibly go wrong 😉
More fun than skipping stones.
Potassium has an even bigger bang.
