Today Year 2 have had fun experiencing chemical reactions. We have watched bicarbonate of soda react with vinegar to extinguish a flame, with have created a foaming fizzy potion using bicarbonate of soda, washing up liquid, lemon juice and food colouring to add effect. Our favourite experiment was the marvellously minty geyser where we watched what happens when Mentos mints are added to diet cola! The result was EXPLOSIVE!!!
