We made our volcano a cinder cone volcano. We put cardboard together and painted it brown. Red for magma. We made a hot spring also.  For the expiation we are doing diet coke and mentos and for the hot spring we are doing vinegar and baking soda. Maddie and Olivia were in my group. Here is the picture:

As we dropped the hot water into the  cold water it started to slowly go up and then around to the outside and down to the bottom. It would keep doing thing this over and over.
