Why does shaking a container of soda make it "explode" when opened?!

the pressure in the bottle does not increase when you shake it, but is still to blame for the phenomenon. In an unshaken bottle, soda occupies the bottom nine-tenths of the container, with a pocket of gas siting on top; this gas escapes with a pfffffft when you open the bottle, leaving the soda undisturbed. When you shake up the bottle, though, some of that carbon dioxide is mixed into the liquid and forms tiny bubbles. The gas still wants to escape when you open the bottle, though, but now has to muscle its way up through the soda toward the spout. In doing so, it pushes the liquid upwards, causing it to gush out of the bottle. The more you shake the bottle, the more thoroughly the carbon dioxide mixes with the soda, the greater the subsequent explosion.
Because a soda can or bottle is a pressurized vessel. The gaseous CO2 is in equilibrium with the liquid and vapor phase in the can. Agitating the can removes this system from equilibrium. What you get is essentially a greater build up of pressure. This results in a greater pressure differential between the can and the outside air. Which in return makes it flow out faster.
Soda is a carbonated beverage. When you shake the soda, some of the carbon dioxide comes out of liquid solution. When you open the can, the rapid decrease in pressure causes even more of the carbon dioxide some out of solution.
yes i agree with andrew.....have u ever heard of "the bends" aka decompression sickness? your body can pop just like a soda can except its from pressure changes from going high in the sky or underwater.....thats why youre not supposed to ever dive and fly in the same 24 hour period.
Because of the carbonation ; the soda is carbonated, so when you shake it, the force of the carbonation makes it shoot out.
dr pepper!!!!!!!!!!!!!!
its just one of those things.. haha
