Glassblowing is fascinating. It is only in glassblowing that one can take something that is so hard and brittle and fragile and turn it into something that is soft and viscous and ductile. Hot glass is runny; hot glass can bounce or squash if dropped on the floor; hot glass can be cut, pounded, squeezed, blown, or caressed into any shape. Hot glass can be transformed into something that at room temperature will again be cold, hard and still.
