Wonderfully messy! There was only enough citric acid for one go round with this set.

My almost 8 yr old son was totally captured by this volcano becoming slime experiment! He could not believe that adding all the provided ingredients and following instructions actually made slime!!! Thumbs up to this one!!!


We loved how this was more than just making slime. It taught my girls about chemical reactions and polymers so they understood what was actually happening during the experience. Highly recommended!
