How do you make, or where do you buy, a sheet of sugar glass for filming. The scene is two kids stuck in a car and a man smashes the car window to get them out. However because I have no budget to break an actual car window, I was thinking of making/buying a sheet of sugar glass (or other easy to break glass look-a-like) and placing it on the window (while the actual window is wound down) and then having the man smash the fake glass.
Is there another brand name/ type of glass I should be searching when looking to buy?
