How to break/open?
The secret to breaking ampoule glass vial safely is wrapping the vial with something thick and cushiony so that the pressure exerted to break the glass will not crush the upper part of the glass.Let's study the anatomy of the glass vial. It is made with a small bottleneck with white line that indicates that you should break at this point.

Why such design?
In physics, the sudden bottleneck makes this point a weak point. So when extra pressure is exerted at this weak point, it will snap and break into half. That's how you get the content easily and safely. When you use cushion surface to wrap the vial, the pressure will be transmitted into the soft surface. That's how you prevent the upper part of the ampoule to be crushed. Try to feel the location of weak point and place your fingers from both directions a little further about 1 cm apart.
