One of the things we like to do is make a home-made volcano. The visual effect really fascinates the boys, even if the science eludes them.
A couple of weeks back, someone told me that Diet Coke and Mentos created a spectacular effect. So I looked it up and what an eye-opener!
A search on Youtube will call up hundreds of Coke and Mentos home experiments, though the above is far and away the most spectacular – and spectacularly wasteful! – of the lot (and apparently sponsored by Coke and Mentos).
I meant to do some research to figure out a less wasteful, toddler-safe, way of doing it. (Would a smaller bottle and half a Mentos work?) But Porthos caught me watching these videos and immediately said, “I want to do that.” Sigh.
I have a week of vacation leave coming up year-end. Watch this space….
