how does a shaken can of soda lose its pressure over time, if its sealed?
In: Chemistry
Because when you shake the can, it gets angry little bubbles mixed in the soda that cling to the inside wall of the can. They’re so mad because they’re under so much pressure and have a lot to deal with, and you’re just making it worse for them. Over time, they calm down though, and instead of being disturbed inside the liquid, they let go. The angry bubbles float up to the top of the can, and are no longer mixed inside the liquid. When you open the can, since there isn’t any soda in the way now, you just get a burst of gas.
For a fun experiment at home, shake up a can of soda real good. If you opened it now, you’d paint the room with soda and make your parents mad. BUT, before you open it, flick the sides of the can all around, as hard as you can. Snap your fingers and then pop the top! Guess what, no mess! Impress your parents and show them the cool science you learned on the internet!
