Diet Coke and Mentos; the winter version - YOUR IDEAS NEEDED

OK, for Kenny and Larry and anyone else, don't put the Diet Coke and Mentos in your mouth. Just open the soda bottle and put the Mentos in the bottle.

In a warm air setting, you can restrict the flow of the soda to make the guyser higher. One way is to drill a small hole in the cap and put it back on the bottle. Before you put the cap back on the bottle, thread a string through it and attach the Mentos so you can release them down into the soda. Daughter created a 'cage' for several Mentos using some wire twisty ties such as from bread bags.

So here are your steps:
Drill a hole in the soda cap.
Make the wire basket to hold the Mentos. Try 5 or 6 Mentos pieces.
Tie a string to the end of the basket and thread the end of the string through the hole in the soda cap.
Hold the string taut to the top of the cap so the Mentos are NOT in the soda.
Reattach the cap.
Go outside! Continue to hold the string taut to keep the Mentos out of the soda.
Set the bottle on the ground carefully. Release the string to drop the candy into the soda..
Step back and see if it guysers. Some people have had it go almost 30 feet high.


If you figure out how to get it to work in the severe cold so that it snows Diet Coke, please tell me how you did it.

Kenny, take pics.

How cold do you think it will get? The early morning is the best (coldest) time.

See the tips I gave in the post above.

Kassandre's sister did the coke and mentos thing last summer. It was VERY hilarious when the coke erupted in her face and went everywhere.

Your experiment sounds very cool, and I hope you figure out something that works well. It will be cool to see the video.

I can't help with the Diet Coke and Mentos (that's a very popular science fair demo!), but what about blowing bubbles? Perhaps not as explosively fun, but don't they freeze if it's cold enough?

Dol, I don't know. We need to add that to our next -20F experiment day. We don't get days like that all the time, so it may be a while. That's why it's best to have the plan ready beforehand.

Thanks for the suggestion!

How about a nice indoor activity? This is always popular.

I think that pic is more disturbing than my friend on WoW charming a bunch of maggots. (We were in Naxxramas after all.)

Photobucket. No one I associate with would do that anymore.
