Instructions
Fill a 3-inch tall plastic tray with sand. Moisten the sand with a small amount of water and press the sand down with your hands until it is firm.
Make the mold for the plugs. Place a plastic bottle cap top- down into the sand. Press the cap firmly into the sand then remove to make a circular indentation in the sand. Use a pencil to push a 2-inch deep hole into the center of the circle. Repeat the two-step process to fill the sand tray with plug molds
Mix the cement in a small plastic cup according to the manufacturer's instructions, then mix in an additional 1 tbsp. of water. Continue to add 1 tbsp. of water at at time until the mixture has a soup-like consistency.
Use the plastic cup to pour the cement mixture into each plug mold. Let the cement set for 48 hours. Remove the plugs by gently loosening the sand surrounding the mold and lifting the plug out. Allow the plugs to dry for an additional 24 hours before use.
