Will wax stick enough together to pull it out easily from a small hole?
Can you blowup wax to a ball or dos it has to be full of was? If full than how to get it out before it turn to liquid or sticky mass?
Is there a type of plastic that has a low melting point or better a low soft temperature?
What we need is to blow up a ball (3-7 cm in diameter), cover the ball except a 6mm hole, let it dry, and then removes the plastic ball through the 6mm hole.
So to remove the plastic it needs to be soft...
