Pushing Glass Tubing Through Safely
Forcing glass into rubber is a common cause of cut hands. Smooth the end of the tube first, wet it and the hole with water or glycerine, wrap your hands in a cloth, and feed the glass in with a gentle twist while gripping it close to the stopper. Ease a stuck tube out the same way instead of pulling straight.
