The Diet Coke and Mentos Experiments

Now if only science experiments in schools and colleges were like this!

What a great way to learn about the contents of carbonated beverages, a common candy, materials science (the surface of the Mentos), theories about boiling, phase transitions, nucleation sites… and more!

(If you’re too lazy to wait for the video to download and watch it, it’s these two guys from eepybird.com who have made very elaborate fountains using Diet Coke and Mentos. Put a Mentos into a two litre bottle of Diet Coke and voila, instant fountain. Of course, it’s more complicated than that, but still relatively simple. Watch the video, it’s a lot of fun! And well choreographed!)
