Root Beer Floats – States of Matter Experiment


In Science Today, 2A got to observe a reaction between a liquid and solid that releases a gas using simple ingredients of root beer and vanilla ice cream. This was the perfect way to end our States of Matter Science Unit. We also loved eating our yummy experiment.

Feel free to try it at home!
