TALLAHASSEE, Fla. (WTXL) - Halloween is right around the corner, and is a great way to have a little bit of fun with the kids. Here is some fun you can have with dry ice, just make sure an adult is there to take the reigns on this one since dry ice can be dangerous if handled improperly.

Make sure you have a nice sturdy pair of gloves when handling the dry ice since it is 109° below zero, you're going to need a measuring cup, dish detergent, distilled water and glycerin. Using these tools, you are going to be making a bubble with the dry ice.

Measure out 1 cup of distilled water, add in 5 table spoons of dish detergent, and then add 4 table spoons of glycerin, which you can find in the pharmacy, to a bowl. This will help to make the soapy substance a little thicker so we can end up making a larger bubble. Once all of the items are in the bowl, mix them together. Next, cut a thin strip of cloth and dip it into the solution.

Put the dry ice into a bowl with a defined lip and add water. Keep adding ice and water until the gas is flowing over the edge of the bowl. Take the soapy cloth and run it on the edge of the bowl.

The bubble will slowly start to form and as the solid dry ice breaks down, it turns directly into carbon dioxide gas. This is a process known as sublimation. The gas is captured beneath the soapy solution until the container can't hold it any longer and bursts!
