It's so easy! Wrap foil around a mason jar. ... Inside the mason jar, put the following: water, 4 spoonfuls of baking soda, a small squirt of dishsoap, and a few drops of food coloring. Activate the volcano by adding vinegar. After the lava stops flowing, just add more vinegar to make it go again.

Ingredients Cardboard. Three 4-oz. plastic cups. 1 teaspoon ARM & HAMMER™ Baking Soda. Plaster of Paris. ¼ cup vinegar. Liquid dish soap. Water. Red food coloring.

The centre of a volcano is called the central vent. At the bottom or base of the volcano, you will find magma. This is hot, molten rock from the center of the Earth that has found its way through the Earth's crust.

The crater is the bowl shaped opening located at the top of the volcano. The crater is also the steep sided walls made of hardened lava that surround the main vent.

Place the water, soap, food colouring and vinegar in the drink bottle. Wrap the baking soda in the tissue and drop into the bottle. The volcano model will then erupt. The volcano can be made more realistic by enclosing the structure in home made play dough.
