well, he always could do things the hawaiin way, and eat the inside of an aloe plant. They say that it helps, though I've never tried, and doubt I ever will, since it smells like all hell

Uh the soda thing...
I'm guessing why that works is because all you're drinking is warm water with sugar in it. The sugar doesn't do anything for you, it's just the warm water that helps. That's why you drink tea: the warm water helps, and the herbs do too.
Boiling soda just forces all the carbonic acid to turn into water and carbon dioxide, and the carbon dioxide leaves the solution. So you're left with sugar and water.
Eating an aloe plant... that can't be good for you, can it? eek

actually it is, surprising as it sounds. the inside of the "leaves" are actually like a pulp, and there full of all sorts of nutrients and vitamins that'll help you out alot

You don't really boil it you just get it untill it's flat.

Yeah, warming it will do that too. It'll turn it into warm water.
See, according to Le Chatlier's principal, whenever a stress is added to one side of an equilibrium, the equilibrium will shift to reduce that stress. In this case, the equilibrium has carbonic acid breaking down to form water and carbon dioxide, and most of the carbon dioxide escapes, so none of the water can combine with it to form more carbonic acid. The reaction proceeds until it reaches equilibrium. Now, when you heat the soda, you're applying stress to the carbonic acid still left in solution. To releive this stress, the equilibrium shifts more toward the products, forming even more water and carbon dioxide. The CO2 escapes, and you're left with just water in solution, which can't recombine with anything, since the gas left.
Ta daaaa!

I found it rather interesting. 3nodding
I love science, but only the cool stuff like that, not the boring theories and the equations and crap. 3nodding rolleyes

How about blowing up Pringles cans for showing how oxygen and hydrogen react?

Hm... uh... yeah. Alright.
Or, how about this! A fun mini-implosion you can do in your own home! Take a soda can, and put a little bit of water in it. Not too much. Heat it up (on a bunsen burner ideally, but any other way is OK too. Don't burn down the house, kids!) until the water boils. Have a big ice water bath ready, and grab the can with a pair of tongs. Quickly turn it upside down and into the icewater bath, so that the opening of the can is submerged in the cold water. There will be a huge BANG, and the can will impload, crushing itself into a flat pancake like structure.
It's simple: the warm water vapor that fills the can when you boil the water gets chilled really fast when the cold water hits it. Its volume shrinks rapidly, and since the can is sealed (the only opening is under water) the can gets crushed. I think that's how you do it....

but that takes all the fun out of it sing. Another science thing is to light some magnessium on fire and put it between two blocks of dry ice. The magnessium is so reactive that even the CO2 wont extinguish it. I learned that on Chemistry last year
