Diet coke and mentos

We all know and love the soda bottle rockets. When you get a liter of diet coke, a roll of mentos, you don't only have yummy foods, you have a rocket. When you put the mento in the coke, the soda shoots high into the air. Have you ever wondered why? The mythbusters did. If you look at a mento close up, it has a surface like the moon. It has craters. When you put into contact with carbonation, the CO2 catches in the craters and forms into a gas. That, along with the carbonation that's already formed, allows the drink to shoot up into a beautiful, sticky soda column.
