Why Does Shaken Soda Explode

Shaken soda explodes because of a gas that put into the soda itself. Soda is made up
of 3 different things:

1) syrup
2) water
3) carbonation (a gas that makes the soda bubbly)

Carbonation,water and sugar aren't really good friends. Sugar and water like to
hang out together and mix well, but carbonation (the little fizzy bubbles) are
always trying to escape. When you shake the bottle, the carbonation bubbles get
excited (more like angry, much more than they were before), and they push really
hard on the inside of the bottle. This creates what's called "pressure" inside the
bottle, and when you open it, that pressure is released...and the fizzy bubbles are
trying really hard to escape- but while they're escaping, they fling water and
syrup at you in the process.  :( Bummer.

Ways to Open a Shaken Soda Without It Exploding:

Tap for a few seconds on the top of the bottle. This causes those little angry
carbonation bubbles to settle-down and get more calm so you can drink the soda.
You might have to do this a few times before you don't get sprayed.
