At Munchkin camp this week, Neve made a papier mache volcano. They made it erupt in class and they got to bring it home. So of course, we had to try it here too!
1 cup of baking soda
1/2 cup of warm water with some dishwashing liquid in it. Don't forget the dish liquid. we did the first time. It helps to slow down the eruption. Mix the baking soda and water together.
1/2 cup of vinegar. you can add food colouring to it.
and if you really want to drag it out, just pour a bit at a time.
it was a fun little project. I think i just may have to get some coca cola and mentos though!
