A good cook can't cook another good cook's cookies becasue they've already been cooked by the other good cook.
I'm not too sure about that, but I do know that glass cooks things quicker. Since glass is clear, infrared waves from the fire in your oven travels through the sheet and hits the cookies directly (radiation), as opposed to a metal sheet which must absorb the heat waves then transfer them into the cookies through conduction. Of course, both types of oven still use heat transfer through hot air, known as convection. Because the glass cooks quicker, you may be overbaking the cookies so they set in the oven and then cannot fall once they come out. That's just a guess though.
Cookies come from Websites that you visit, across the Internet, and into your PC.
