Build Your Own Balloon!
There is a definite advantage to being able to make your Volcano bag as small or as large as you would like. A smaller bag is great when you don't want to have a large bowl loaded, and no one can resist the fun of being able to fill a four-foot long monster bag. You'll need the Solid Valve set to make your own bags. This ten-foot roll easily cuts to size and comes with instructions on securing the new bag to the valve.
