latex prototype

Because of the wrinkles, I am trying to use latex to make the inner shell.  Latex is stretchy and should form better to the amputee's leg.  The weather balloon provided one source of latex.  Using contact cement, I connected the balloon to the outer plastic shell and made the full shape.  The weather balloon functioned well when attached to a vacuum with a bottle inside.
