They were handing out free Mentos at Charing Cross the other week – I couldn’t resist introducing them to some diet cola…
A colleague had tried it with no luck, so perhaps the trick is to do as we did, and warm the cola in a bowl of hot water from the kettle. A smaller nozzle and pin to allow controlled dropping of the Mentos would be good ideas too. I could only get the first Mento to fizz – I added 4 more and nothing much else happened.
Fantastic! I tried this a few times and never managed to get it to work (the Coke just oozed out of the bottle). I was ready to start combatting the Mentos-Coke conspiracy to boost sales on the basis of an experiment which didn’t really work.
Must be the hot water… will have to try again!
Excellent! Looks like very good fun.
William and Henry are fab – how old are they now?
William is 5 and Henry will be – omigod – EIGHT in a week or two…
