4M: KidzLabs - Fizzy Bubble Lab

We've burned through a whole bottle of vinegar in one afternoon, the fizzing experiments are that addictive. The instruction booklet is clear enough that my 7-year-old could set up most of the reactions herself, and the look on her face when the foam erupted was priceless.

The bubbling reactions kept my kids entertained for over an hour, and I loved that all the materials needed are common kitchen items. The instructions for the different fizzing mixtures were clear enough for my 7-year-old to follow with minimal help.

We set up the volcano experiment on a rainy afternoon and the foaming reaction was way bigger than we expected, which got both kids screaming with joy. The instructions are clear enough that my 7-year-old could mix the baking soda and vinegar steps on her own.
