Has anyone tried the diet coke and mentos experiment? If so, how did it go?
I haven't tried it, but saw it on Mythbusters!!
Hahaha! My friends and I did that once in our free time over the summer...we heard a rumor about it, tried it, and then we started seeing it all over TV! It actually works quite well, if you can figure out how to slip in the mentos quickly so the explosion is impressive. But it does work! If I were a science teacher, I'd definitely include this in a lesson somehow.
What happens? Never heard of this
Here's a link...
Ohh, I asked about doing this on another BB for volcanoes...
I went to that site and watched the Pepsi Girl video (under the link for cautionary tales). I laughed SO hard! If you need a good laugh today, check it out!
In theory, you basically add mentos to a two liter bottle of diet soda (coke) and the soda bubbles so rapidly that it shoots out the top of the bottle like a gyser. Very cool, and exciting.
I saw it when they did it on the news...... they had lots of bottles set up.... it was fun to see.
The gifted teacher at my school is doing a whole project on it with his students. He hasn't started yet, but it looks like lots of fun!

A lot of our kids want to do this for the science fair this year. Maybe I should show this video!
Here is the deal on the mentos and coke thing, it works great...but it is really messy. I modified it. Insead of dropping them in and running before the stray (good luck) I drilled a hole in the top of the soda cap. Then I used a needle and dental floss and strung together 3 mentos. Then I put the thread in the hole in the cap. Then I screwed on the cap and let go of the string. there you go, all the fun with out the mess, and the spray lasts longer because the hole is smaller.
That was one of my fave episodes.
One of the only experiments you can replicate safely at home!!
I first saw this done at an early childhood convention. The presenter was a representative of Steve Spangler, who has all kinds of neat science stuff!
The rep used one of Steve Spangler's "test tubes" to put the Mentos in - but, she said that you could also use a rolled up piece of stiff paper to make your own tube.
Yes. It is awesome. My 4th graders loved it. Do it outside. Use diet soda. We expweiments with 2 and 3 liter sodas because of the width of the mouth of the bottle. Then we demonstrated how it works using kids as examples. Two kids wrapped their arms around another kids to "hold" him in place. This was the water molecule holding in the carcon dioxide molecule. Another kid ran up to them and broke the arm chain. This was the mentos. The kid in the middle is released as is the soda. They loved this. It is a great deal of fun, but very messy!
yes, but dont use diet coke... you want the sugar and carbonation and for cleaning purposes use a CLEAR soda. YOU MUST drop the mentos in, like slam them in quickly at the same time. DONT drop them in one at a time....
Here's his website. Lots of great ideas!
Thanks to all who have responded, I can't wait to show this to my kids tomorrow. It should be a blast (literally )
I did this with my boyfriend's little brother at his birthday party. . .we got the small bottles of coke, which worked pretty well because a copule mentos used most of the soda in the bottle. very very messy, but great fun

So which is the best soda to use?
I'm going to do this with my first graders when we learn about geysers. The other teachers are going to think I'm nuts. It's okay if it's messy... I'll do it at the end of the day.
My son just did this in his freshman science class. Is this a recent discovery? I've never heard of this before, and now I'm hearing about it a lot.

This experiment is a special thanks to the show "Mythbusters" where they were trying to prove/disprove a myth of a kid drinking a diet soda and eating a roll of Mentos having to be taken to the emergency room.

Mythbusters proved that the ingredients in diet coke provided the best reaction. Other sodas work, but diet coke gives a bigger tower.
I first saw this at my son's graduation party. I thought they were crazy (my son and his friends) but they did it and it worked great. Even all of my older relatives got a kick out of it.
