Fill the squeeze bottle with tap water. Fill the lubricant reservoir with water from the squeeze bottle. Check for leaks at the edges of the clay reservoir, and seal any you find.
Don your gloves and safety glasses. Glass is a hard, brittle solid and whenever you drill it you run the risk of shattering the bottle and injuring yourself. From this step on, you could injure yourself or those around you so work slowly and with care, and always wear proper personal protective gear.
