4 Cover a table with newspaper or plastic. Put some sand in a container and add a little bit of water. Use the sand to make a cone shape on the newspaper. Put some water in another container and sprinkle some plaster into it.

5 Mix the plaster into the water until it is as runny as a honey. You may need to add more plaster to make the mixture thick enough. Pour some plaster over the sand cone and smooth it with a wet paint brush. Make a hole in the top of the cone about as big as a ten cent coin. Let the plaster dry for one day.

6 Remove the sand from inside the plaster volcano. Make more plaster. (See Steps Five and Six) Put the plaster volcano on a paper plate and pour some more plaster into the plate so that the edges of the volcano are all covered. Let this plaster dry for one day.
