After seeing the Big Version, the boys wanted to try it out. We finally did (in the safety of our bathroom), and here is what happened.
As you can hear, Athos was NOT impressed. (Would two Mentos would have worked better?) Anyway, I decided to post it as our little contribution to human knowledge and endeavour. It’s a dreadful waste so we’re unlikely to attempt this again soon. Let us know if you do, and whether two works better than one!
