Vinegar and baking soda from your own kitchen, and eleven experiments that fizz, foam and race across the table. That is the deal 4M makes with KidzLabs Fizzy Bubble Lab, and it is why an eight year old can be running a chemistry lab within minutes of opening the box.

The projects are the kind kids talk about at school the next day. A tabletop volcano that erupts in pink foam. A rocket racer that fizzes itself across the floor. A foamy monster that oozes green through its teeth. A lava lamp tube full of drifting colored blobs. The kit supplies the tubes, the volcano cone, the racer, the monster stand and the fittings; you supply the vinegar and baking soda, which 4M says plainly are not included.

4M prints FOR AGES 8+ on the carton, and one experiment uses a balloon, so an adult stays close. Eleven fizzy science projects for one rainy Saturday, and most of them can be run again and again.
