Create, erupt, explore — a sensory science adventure for curious little hands. This isn’t just a fizz experiment — it’s a whole world to create and explore. Build your volcano from soft brown playdough, surround it with blue swamp slime, and fill the crater with red lava fizz. When you’re ready, pour water inside to trigger a bubbling, foaming eruption! After the eruption, the adventure continues — children can mix and mash the fizz, slime, and playdough together into a gloopy sensory delight, extending play long after the volcano has blown.
