SciShow Kids recently published an updated video about a “classic” science experiment. That experiment is dropping Mentos candies into a bottle of soda pop. But before doing that and explaining what happens, the video briefly explains how beverages are carbonated and why the bubbles stick to some objects better than others. If you’re looking for something fun and educational to do at home with your kids this weekend, watch this video then do the experiment. I think we’re going to give it a go this weekend.
For some printed directions on how to do this experiment, take a look at this PDF from the National Council for Special Education. And for a variation on this experiment take a look at the Diet Coke and Mentos Race Car activity published by Carnegie Melon University School of Computer Science.
