Modèle d'apprentissage de volcan en éruptive avec ressources d'apprentissage

Good size and includes detail on inside. Slightly stiff to take apart when two sides are joined together, so hoping it will withstand multiple uses by multiple schools.

This was a waste of money, in my opinion. I usually don't write harsh criticisms but the thing was a dud. It's very large. I did not expect the eruption to go sky-high, but we followed the instructions to a t and the "lava" just sort of dribbled down the side. Tried it again with more baking soda, same vinegar and it was marginally better. Underwhelming to say the least and a disappointment to my grandson. I think the tube that you put the ingredients is too small for the size of the volcano.

They couldn't wait to do this! I didn't get the solution correct the first time so they were a little disappointed but that was my fault lol.

I have used it with my home schooling for science. My Grandson it really liking the experiments that we've been doing and your volcano has been a great teaching tool as how volcano's work and the cross section of it shows what the inside of a volcano is like. It's better than any picture in a book.

The product is great only problem is to clean to take apart the volcano.
