Hi everyone, Im a newbie with a problem. Im a art student and I have recently made a piece with pm (not having used it since I was maybe 8...) and I want to continue with it, but am having structural problems. First of all, I constructed a base from 2 by 4s and dowels, 15 feet high. Then I pmd balloons in various sizes and tied them to the base from the bottom up so that they taper in size from largest at the bottom, to smallest at the top. It was inspired by the exhaust plumes created by rockets when they take off, and I am very pleased with it. Problem is since it was so big and I only had a little time to make it, I only put one layer of pm on most of the balloons. I would like to be able to add to it, and move it for exhibit. but logically it is to flimsy.
   My question is this, aside from just adding more layers of pm, can anyone suggest a way to make it more structurally sound? Im hoping there is a cheap, liquid I can paint on or spray on that will add a structural layer. Any suggestions would be greatly appreciated.
