The volcano experiment was a huge hit with my 7-year-old, and the included lab supplies made it feel much more legit than just using baking soda and vinegar from the kitchen. It kept her busy for the whole afternoon.

We’ve already grown two batches of crystals and the instructions were clear enough that my kid could mostly run it solo, which is a huge win. The lab supplies feel sturdy for the price, and it’s genuinely fun watching them mix and measure like a real scientist.

The volcano eruption had my six-year-old shrieking with joy, and the included supplies meant I didn't have to scramble for extras. Even the cleanup was easy, which honestly surprised me.
