Our teacher was telling us about how the change in pressure on top of a volcano can either make it erupt or have it not to erupt. One of my friends decided to ask a question that would soon lead to something fun.
Friend: I don't understand. *asks*
Teacher: (brings a bottle of water) Okay. Look.
Me: Uh, that water has gas in it, so don't shake-
Teacher: Yes, yes, yeah. Think the cap as 'pressure'. Even if I shake
the bottle like this, the pressure doesn't let it come out.
Uh-oh.
Teacher: So, if you don't have the pressure to block the way, you-
What the fudge?!
-you get a mess.
I told her. I did.
Conclusion: Water with gas + shaking = fail.
Don't try this at home.
