1 Use a sheet of plywood a minimum of eight inches wider and longer than your planned volcano to form the bottom, to stop the lava from staining surfaces throughout eruptions.
2 Use salt dough, plaster or papier-mâché to make a mountain around an empty 2-liter bottle placed upright at the middle of the plywood base. take care to depart the lid off.
3 Form the model volcano's open prime tightly round the mouth of the bottle.
4 Make ridges and channels starting at the volcano's prime and ending at the bottom of the volcano for the lava to flow through.
5 Let the volcano dry utterly, then paint it with acrylics or spray paint. Plastic aquarium plants are often clipped and glued to the volcano for trees.
6 Spray the volcano and plywood with a transparent sealant once the paint has dried.
7 Mix 1 tbsp. liquid dish laundry soap, 1 tbsp. baking soda and many drops of red food coloring during a cup.
8 Pour the mixture rigorously into the bottle.
9 Set the volcano in an open space, ideally outside.
10 Pour 1/4 c. white vinegar into the bottle and stand back to look at your volcano erupt!
