4M Kidzlabs Volcano Making Kit - Diy Geology Chemistry Lab Stem Toys Gift For Kids & Teens, Boys & Girls, Model:3431

The kit contains plaster powder, a volcano mold and a few colors of paint to decorate the plaster once it fully dries. The paints weren’t enough or maybe my kids were heavy handed but you can basically use any type of acrylic or even water based paint you have at home. We kept the mold and reused it with a pack of plaster of Paris I bought elsewhere a second time as well. You will need baking soda (sodium bicarbonate) and vinegar to create the volcano effect yourself. We added a bit of red food coloring to make it look more like lava. Kids loved it. One of them got a star sticker for his effort from his science teacher. Mold seems sturdy and flexible enough to last a long time. Money well spent. I suggest you take the experiment outside into the yard for an easy clean up. I let the volcano dry under the sun for an hour and took it back inside. You can use the volcano many times as long as it is dried fast after each experiment. I’m guessing the plaster would suck up the excess vinegar and get soft if it isn’t dried properly. It’s hot enough outside anyway.

Very nice idea, my kids liked and enjoyed it

In small print on the box- no vinegar or sodium bicarbonate included( which makes the lava) Therefore it's just a kit to make a the volcano crater
