Drop a pack of Mentos in a two-litre bottle of Diet Coke and you get yourself a nice soda geyser. It's fun! It's also pretty wasteful! With this kit you can at least tell yourself you're using Mentos' magical properties to propel a little plastic car up to 60m.
The kit come with a car that can accomodate a standard two-litre soda bottle as well as a handy cylinder for sliding the sustainable fuel pellets (Mentos) cleanly into the sugary fuel tank. Chemistry takes care of the rest: the car zips along at a pretty impressive clip up to a distance of 60m. It'll be available to all aspiring cool science teachers later this year. [Be Amazing Toys]
