What did I do wrong?

[iamaelephant]

So I've seen all of the videos with guys making a fountain out of a bottle of pepsi and a mentos, and me and some mates were drinking in the weekend. I thought it would be a cool idea to show them. Went to the service station and picked up a bottle of coke and a pack of mentos. Chucked about 5 of them into the freshly opened bottle and it wad pathetic. Why didn't it work for me? I mean, it fizzed up but just sort of dribbled out, not like the fountains I've seen on the internet videos. I usd coke, not pepsi. Does this matter?

the reason for diet pepsi is only less sticky.

lol, why mentos? You're suppose to use alkaseltzer(sp?).

not diet pepsi......DIET COKE.

It is amazingly fun

Also, watch Mythbusters this week, they have an episode devoted to this.

You're supposed to drop the entire roll of Mentos.

Most of the videos I see on youtube are mentos. Infact, i havent even seen a alkaseltzer video yet but im sure its the same thing.

They're having this topic on a new episode of Mythbusters this Wednesday.

Diet sodas/pop has a lot more carbonation than regular pop/soda.

Don't you have to use a tube so you can feed them all in there at once? I think on Mythbusters they used a tube with a piece of paper under it sitting over the mouth of the bottle. Then they yanked the paper out let the Mentos drop in and ran like hell, lol.

I used to do this with Sweet-Tarts as a kid. IIRC, it worked pretty damn fine but nowhere close to 'fountains'.

No, you have to use a 2lb bag of Mentos!

Actually, diet loses its carbonation easier. Easy demonstration to verify: Go to your corner gas station convenience store, purchase a 32 ounce coke and 32 ounce diet coke (or pepsi/dt pepsi) Fill both equally up to the rim. Put on lids. The diet will soon be coming through the straw hole because of the volume displaced by carbon dioxide bubbles forming on the surface of the cup.

While I'm not certain about the amount of carbonation used in the bottling process, you can refer to my example above (pop/soda from a fountain). Both regular and diet colas use the exact same carbonated water, thus have the same amount of carbonation in them. Diet seems to be more carbonated simply because it bubbles more - why? Because it's more unstable.

It works out the same either way, but noted.

I've yet to try this, though. Gotta go get some mentos soon...
