The balloons must first be heated to regain their elasticity, which is robbed from them in storage by the -4 degrees Fahrenheit surface temperatures in the southern hemisphere's summer.
In this paper, elasticity polishes material using polyurethane for polishing arbitrarily curred surface is presented.
