The Art of Effervescence
As Henry’s Law shows us, the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. If the pressure is increased, the gas molecules are “forced” into the solution since this will best relieve the pressure that has been applied. The number of gas molecules is decreased. The number of gas molecules dissolved in solution has increased. When the bottle is opened, the pressure above the solution decreases. As a result, the solution effervesces.
As our latest project for Coke shows us, all this can lead to a lot of fresh, playful interactivity.

You misspelled interactivity, goofer!

Dude, you can edit!

yeah but its more fun to point out when you misspell something.

Also don’t forget Le Chatelier’s principle that says the heat or enthalpy change of the dissolution reaction of most gases is negative, which is to say the reaction is exothermic. As a consequence, increasing the temperature leads to gas evolution so keep that soda cold my friend.

beautiful, imaginative, fun work.

it is cute, but how do you get to the content?
