About The Extreme Diet Coke & Mentos Experiments
This is the video that started it all: a backyard experiment became a cultural phenomenon. This is what happens when you combine 200 liters of Diet Coke and over 500 Mentos mints! Click here to read more of the amazing Coke & Mentos story.

How Does This Work?
What makes the soda fly out of the bottle? Will you explode if you drink Coke and eat Mentos? Click here to find out!

Try This at Home!
Yes, you can try this at home! You can get your own Coke & Mentos Kit, which includes nozzles just like the ones we use, or you can click here to learn how you can do it with stuff from around your house.

    THe reaction is caused by nucleation, where the tiny pores in the mint produce gas(bubbles). EepyBirds rule!

    Science, baby, science! Just don’t blind yourself with science…..note goggle use!!!!!!

  • Manzi

    The whole video I couldn’t help but think about the waste that was going on here…

  • Willow

    This is fantastic! The timing is awesome! I want to show this to kids here at my school, but they’ll think the normal 1 bottle demo we do for them is lame after this haha!! And as for people making comments about where the money comes for this, I highly doubt they’re dipping into tax coffers for this… I mean seriously… and even if they did, I’d rather my tax went on something like this than government fat cats holidays and expenses.


    How much money did you spend on coke & mentos?

    Diet Coke and Mentos Machine.

    Engineers at the Department of Chemical Engineering built a machine that
    uses Diet Coke and Mentos to produce power. The Mentos candy reacts with the Coke and the foaming liquid bursts out of a nozzle to make a spool spinning. A fishing line connected to a lego car is wound up on the spool and gives the car a speed of 40 km/h.

    That wasn’t really an “experiment” as such. It was more like a “show”.
