    hubble bubble boil and trouble

    The Open University was having a big sort of ‘village fete’ to celebrate its 40 yrs in education so we went along and one of the things we got to watch was ice-cream being made using liquid nitrogen.

    Jean and another little girl picked the flavourings and then we watched.

    First off they poured in milk, icing sugar and cream and stirred it and then the chocolate chips and coffee flavouring. Then the vat of liquid nitrogen appeared in the gloved hands of a Chemist. They poured it in and stirred the mix.

    And stirred and what amounts to dry ice frothed forth from the brew.

    And within like 10 minutes we were sampling the ice-cream – Jean went back for several helpings 🙂

    It was a cool demonstration though they needed more flavouring in the mix! The ice-cream also melted alot quicker than normal ice cream would which was interesting. Also there were lots of chuncks of ice exploding out of the bowl so we had to stand quiet far back!
