Probably you've already heard about this:
Diet Coke + Mentos = fire extinguisher ?? (oh well, people loved to call it as liquid bomb instead of fire extinguisher to make you remember that we're living in a global terrorism era...)
"What happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? It's amazing and completely insane." See below for crazy diet coke and mentos experiment ...
Some people just have too much coke and time to spend ;)
They say it can go up to 5 metres high up the sky...
You can find more "home made fire extinguisher" videos on
YouTube, or human experiment on
Google video , or you can find the glory from
Eepybird.com that carries out those crazy experiments. While it's fun to play with, do you want to know how it works ? Below is the explaination from
Eepybird.com:

These chemists are saying that the primary cause is physical, not chemical. Their explanation: nucleation sites. If you have a liquid that is supersaturated with gas (like soda, which is pumped full of carbon dioxide), a nucleation site is a place where the gas is able to form bubbles. Nucleation sites can be scratches on a surface or specks of dust – anywhere that you have a high surface area in a very small volume. That's where bubbles can form.
Mentos seem to be loaded with nucleation sites. In other words, there are so many microscopic nooks and crannies on the surface of a Mento that an incredible number of bubbles will form when you drop it in a bottle of soda. Since the Mentos are also heavy enough to sink, they react with the soda all the way to the bottom. The escaping bubbles quickly turn into a raging foam, and the pressure builds dramatically. Before you know it, you've got a big geyser happening!
Still don't understand what the heck is
'Nucleation sites' ??

You can see nucleation sites in action if you coat the inside of a small glass with vegetable oil. Move the glass around to get a nice smooth coating of oil and then pour in some soda. What happens? No fizz. Why? No nucleation sites. Now sprinkle in some granulated sugar. What happens? Lots of fizz! Why? Lots of nucleation sites!
Do whatever you like with this, just don't try this near the security screening line in any airports, particularly in U.S. or Europe... and don't test this with your stomach too
