I'm not sure the lightly thrown ball can break the polymer layer. Just because the glass layer shatters it doesn't mean you can go trough it.

Hope they don't use something like this 3M polymer layer, because it means you will be trapped for 2 more minutes even if you have the tools to go trough the polymer.
