Spoonimo Posted March 30, 2013 Share Posted March 30, 2013 Greetings everyone!I have a seemingly simple question that has been bugging me for a few days.Obviously, the Diet Coke and Mentos reaction has become quite popular on YouTube, as well as in classrooms.Usually the demonstration accompanies a discussion about the nucleation points on the Mentos that cause the CO2 in the soda to be rapidly released.In order for teachers to save money when repeatedly doing this demo, would it be possible to create artificial Mentos?By this I mean make an object (not sure if any shape would work) that had the same microscopic cavities as the candies, but was made out of a material that didn't wear down when exposed to moisture (making it reusable for future experiments). Additionally, might there be a way to produce a substitute for cola? Perhaps by using a SodaStream machine, or the like. I realize this isn't the most ground-breaking idea ever, but I thought I'd get some more opinions on it's plausibility. Best Regards, Spoonimo Link to comment Share on other sites More sharing options...
John Cuthber Posted March 30, 2013 Share Posted March 30, 2013 A sugar cube also works in place of the mento and I'm fairly sure they are cheaper. It would be interesting to try a bit of sandstone or something like that. Soda water from a soda stream should work pretty much as well as cola.
