Also known as foil or metallic balloons, these balloons are made of a material called "mylar" which is a durable metallic material that has a degree of stretch. Metallic balloons are generally filled with helium so they can float, though there are smaller balloons that are filled with air and then attached to sticks. These types of balloons are most commonly used at fairs, and other celebrations for children, so that the balloon looks fun without floating away during the fun.
