Volcano Experiment - Baking Soda Volcano - Cool Science.
You don't have to wait for your child's science fair to make an erupting paper-mache volcano. Making one at home out of paper-mache is fun for the whole family. Discover how easy it is to create your own lava-spewing volcano using an empty soda bottle for a tall volcano, or a cup for a shorter one.In the case of a volcano, the experiment is making a small controlled explosion. An explosion is basically a rapid expansion of gas in a specific amount of space. A mixture of baking soda and vinegar can give a rapid production of gas in a small area to result in an eruption.Baking soda and vinegar volcano. Print out the Chemistry Experiment directions AND the Chemistry Experiment Lab Report. Make sure you have all of the necessary supplies on hand before you begin. This is a really fun “kitchen chemistry” experiment that your kids, grandkids, nieces, and nephews might enjoy “helping” you with.
The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution. For extra effect you can make a realistic looking volcano.Place the volcano in a large plastic container or large baking pan, and set up the volcano in a wide-open area. Pour warm water and red food coloring into the volcano bottle until filled to the top. Add liquid detergent and baking soda. Pour vinegar in and take a couple steps back.
Help your volcano erupt! Place your volcano in the pan (an eruption can get messy!). Fill the volcano cup with the 2 tablespoons of water. Stir in the tablespoon of baking soda until it dissolves. Measure the 2 tablespoons of vinegar into the other paper cup. Ask your child to predict what will happen when you pour the vinegar into the volcano.
