He told me he copied it out of a book and it was directions on how to make a volcano with just newspaper, flour, and a straw. We didn't have any newspaper, so he taped together several sheets of printer paper. He then had John help him form the cone shape that would be the volcano. He found a straw somewhere (water bottle?) and inserted it where he wanted it.
Aunt Keryn will be impressed (she is our volcano expert in the family)!
