ON THE WEB: DIET COKE FOUNTAINSIt was news to me, but if you drop a minty sweet called a Mentos into a bottle of diet coke, it foams up into an impressive fountain. I know this now because there's a fantastic video on the Eepy Bird web site that shows two extremely manic scientists demonstrating the principle by producing an amazing show of spectacular fountains. Watch and admire their artistic performance, and then read the science bit about why this works. Elsewhere on the site you'll find details of experiments to check whether other fizzy drinks do as well as diet coke. |
