I'm not normally one for posting random links - but this is something that simply must be propogated.

The guys over at EepyBird seem to have spent quite a bit of time experimenting with soda and mentos... the current result of which is an awesome replication of the Bellagio Fountains in Las Vegas.

I'm also very hooked on the song that's playing in the video - which you can find over at audiO*6ody.

enjoy!
