Did not work as advertised
My daughter was so excited to get the poly gel, she eagerly awaited the delivery.  She followed the instructions to the letter and the gel would harden and then break.  She tried several times.  To make matters worse, AMAZON WILL NOT ACCEPT A RETURN.  Since this contains hazardous materials, per Amazon policy.  THEY WILL NOT TAKE IT BACK.  We will try to go through the manufacturer (China!) and see what our recourse is, DON'T SPEND YOUR HARD EARNED MONEY ON THIS.
