Need some help from the TTIS department and/or nubby if he's around...so we're working on the science projects.

And we're doing the which soda spews the most when shaken thing.

So, we're trying to figure out the scientific worth of this thing. I mean, seriously, what worth does shaking up some soda cans and seeing which spews the most have?

So, I'm reaching here. Can I assume that if I shake 2 cans of soda and one spews 4 ounces and the other only spews 3 ounces...can I assume that the one that spewed 4 ounces has more CO2 in it?

If so, that could lead to the speculation that with more CO2, it would take longer to go flat, yes?

Help a brutha?

CO2 also lowers the pH. You could measure the pH using strips if you can't access a meter. - psilotum Jan 3, 17:10
It's not necessarily more CO2 -- it could be a combination of additives that releases CO2 more quickly. - ReluctantCynic Jan 3, 17:08 3
- The balloon idea is a great one. -- nm - nubby Jan 3, 17:13 2
  - Yeah...but we're kinda looking forward to the spewage. :) -- nm - Jim Jan 3, 17:14 1
    - Do both, and see if it correlates! -- nm - nubby Jan 3, 17:14
Propulsion? - nubby Jan 3, 17:07 7
- Dude...that's the kind of thinking I'm looking for. I just emailed you too... - Jim Jan 3, 17:08 5
  - Also, your intuition is right. More spewage = more carbination = takes longer to go flat. - nubby Jan 3, 17:10 4
    - See...this is EXACTLY what we needed. How would we list you in the bibliography? :) -- nm - Jim Jan 3, 17:12 3

        Very much appreciate the help. (From everyone). The propulsion thing and the more time to go flat will do perfectly. -- nm - Jim Jan 3, 17:15 1
        
        Any time. -- nm - nubby Jan 3, 17:20
- (We had a high school student build a rocket with soda and mints last year.) -- nm - nubby Jan 3, 17:07
i think theres a few factors - the amount of CO2 - how each can is shaken (difficult to make consistent by hand) and the shape/integrity of the can -- nm - Guy Jan 3, 17:02 2
- Well...assuming all things are equal. Example, Coke and Diet Coke... - Jim Jan 3, 17:07
- If you can somehow standardize the amount of shaking, that would be great. - psilotum Jan 3, 17:07
*secretly puts mentos into soda #2* -- nm - CQ Jan 3, 16:53
