Our volcano is a Composite Volcano. We made this out of paper mache.  We used cardboard for the bottom of it. and the magma chamber, pipe, and the side vent were all made up of a Mountain Due bottle. We painted the paper mache brown and drizzled red paint over it for the lava flow. at the bottom of the bottle we painted it orange to represent the magma chamber and painted a strip of orange going up for the pipe and once coming off of it for the side vent.
