Soda Geysers in Science Club

The fourth and final round of after-school science club sessions for this year took place on the much requested topic of “Soda Geysers”.

The children had fantastic fun making a variety of soda geysers by dropping Mentos mints into 2 litre bottles of different fizzy drinks. The children learnt that the soda geysers occurred due to the dimpled surface of the Mentos mints giving the perfect location for liberating large quantities of carbon dioxide bubbles from the drinks. Over the 3 sessions, the Dr Pepper brand was found to consistently produce the best soda geysers, whilst Lilt always produced the least spectacular geyser.
