Paper and cardboard volcanoes are easy and inexpensive to make. You have most of the materials in your home. You will need:

a piece cardboard roughly 9 x 12 inches
small vial (film containers work well)
tape
newspaper
aluminum foil
spray paint
spray glue (optional)
sand or ash (optional)
2 cups flour
1 cup water

Step 1. Paper Meche
    Rip a sheet of newspaper into thin strips and put aside. Mix the water and flour until it becomes     a semi thick paste like mixture. Put it aside for awhile, until step 4.

 
Step 2. The Base
    The piece of cardboard will be the base of the volcano. Tape the vial near the center. The vial will be the lava pond or magma conduit.

Step 3. The Interior
    Most of the insides or your volcano will be made out of newspaper balls wrapped in tape. Ball up the newspaper, and create your volcano's shape with them. You will most definitely have to use balls of different size.

Step 4. The Exterior
    Now that you are done with that, cover the future volcano with tin foil, and tape the foil down. Cut away the foil above the vial. You might want to hold the foil in place with a pencil . Cover strips of newspaper with the paper meche’ mixture that you made earlier, and cover the volcano with the paper meche’ for several layers. Let the paper meche’ dry, and paint it black when completely dry. For extra effect, add a layer of spray glue, and cover it with black sand.

The best lava, and safest, is actually a chemical reaction, in between vinegar and baking soda, but it works. Put some baking soda and a few drops of soap in the vial. For added effect, add crushed alka seltzer. Put some red food coloring into some vinegar. Pour the vinegar into the baking soda, and watch your volcano erupt .
