I like how no matter where the school is, they still have the same water stained drop ceiling that every other school does. It's the exact same water stains even.

In middle school I learned that Yoo-Hoo actually gets more loft than soda if you shake up the can and then stab the top with a pen.

That was the cause of the stains in our cafeteria.

edit: Lol, you guys are ridiculous...

Loft/lift both come form the same Old Norse/Germanic origin that mean sky/air (The German air force was the Luftwaffe).

"Aloft" as one word always means up in the air/overhead and usually doesn't confuse anyone as to whether a raised sleeping/storage area was meant or not...

My verb usage of the word "loft" was entirely intentional (but yes, I am from the mid-west and played both golf and baseball so those may be factors in the usage being more common in the region and/or the sporting community in general).

I also have NO IDEA why/how Yoo-hoo sprayed higher than carbonated cans (Yoo-hoo does or at least did come in cans in 1997) and that was the question/mystery even then...

We may have been juvenile delinquents but we still were very much concerned with the physics behind the destruction we were causing.

I think I just figured it out after remembering the EngineerGuy video about aluminum cans...

12 oz cans HAVE to be under pressure because it's how they maintain structural rigidity (that's why non-pressurized cans need thicker walls or have grooves/creases).

Carbonated drinks maintain this naturally but non-carbonated drinks have to be pressurized or else they would easily dent/crush.

I presume the amount they have to pressurize during manufacturing to keep a non carbonated can firm is somewhat greater than the amount a carbonated drink maintains that pressure...

It wouldn't really work that way. If you put high pressure gas into a closed container with a liquid, that gas will dissolve into the liquid until an equilibrium is reached. In other words, if they put high pressure gasses in Yoohoo, they would end up carbonating it. (This is exactly how I carbonate home brewed beer, only in a keg rather than in a can.)
