![]() Volcanoes erupt when red-hot magma seeps up through a vent in the earth’s crust. Eventually the bulge will erupt, and hot wax will flow through the sand and the water to the top of the beaker. ![]() As the wax melts, you’ll hear a faint hissing sound and see a bulge in the sand layer. For the most dramatic results, heat slowly over low heat.Ħ. Wait for the contents of the beaker to be heated slowly. Place the stand over the alcohol lamp and put the beaker on the stand. Light the alcohol lamp using a wooden match (Or use an alcohol burner for more speedy results!) and wait for the flame to stabilize (about one minute).ĥ. Allow the sand to settle until the water appears clear again (about 30 seconds).Ĥ. Carefully fill the beaker up with water, taking care not to disturb the sand. Then pour enough sand into the beaker to cover the wax in a thin layer (about an inch).ģ. You’ll need 2-3 teaspoons of wax at the bottom of the mug. Carefully tilt the candle over the beaker, dripping wax inside. Light the candle wick and let it burn for about 20 seconds. Never put a glass container directly onto the stovetop!ġ. Safety Note: Only use a high-quality glass beaker or liquid measuring cup (such as Pyrex) for this experiment! An ordinary glass jar or drinking glass will likely crack under this amount of heat.
