You can make your volcano smoke instead of erupt.
A volcano is any rupture in Earth's crust that causes molten rock from Earth's interior to burst or leak out onto the surface. While this includes underwater formations, the volcano form familiar to most people is a conical mountain with a hollowed-out rim where its peak should be. Homemade volcanoes are favorites at school science fairs, where students add vinegar to baking soda, which bubbles out to simulate an eruption. Rather than simulate an eruption of lava, you can simulate a pyroclastic flow of superheated smoke and ash from the volcano's mouth.
Instructions
1. Set up your homemade volcano on a hard, flat surface such as concrete. Place a layer of clay at the bottom of the central vent of the volcano, where you would normally mix the baking soda and vinegar. This will create a seal to prevent any of the dry ice gas from leaking through the bottom and out the sides of the volcano. Place a cylindrical container that can hold half a liter of water on top of it and seal the rim of the container with clay.
2. Boil half a liter of hot water in a pot, removing it from heat as soon as it begins to bubble so you do not lose any water due to evaporation. Pour the water in a pitcher and seal it with plastic so less heat can escape. Take the pitcher directly to the volcano outside and pour the water into the cylindrical container.
3. Remove three pieces of dry ice from the container you have been holding them in using the insulated gloves. If you want a larger effect, you can drop in a few more cubes, but five is near the limit for the amount of water you are using. Drop all the cubes of dry ice into the hot water and step back. Reacting to the water, the dry ice, which is simply the frozen form of carbon dioxide, will start to sublimate, turning from a solid directly into a gas. Smoke-like vapor should begin to pour down from all sides of the volcano for several minutes.
