Dancing Raisins Experiment

17th Nov 2023

Did you know that raisins can dance?!  We proved that they can, during STEM week in school.  Carbon dioxide bubbles from the fizzy drink attached themselves to the rough sides of the raisins which caused them to float – they were buoyant!  At the top the bubbles burst and the raisins went down.  It was great fun!
