How to Make an Hourglass Out of Plastic Bottles

You can make a whimsical hourglass out of used plastic bottles.

If you have an excess of plastic soda bottles, you do not have to throw the bottles into the garbage or into a recycling bin. Instead, you can use the plastic bottles to create a whimsical craft. For example, you can construct a giant hourglass filled with sand that you can use during a board game instead of the small hourglass they include in the game box. Everything you need to make the hourglass, besides the plastic bottles, can be found at a craft supply store.

Things You'll Need

• 2 plastic soda bottles, 2 liter
• Sand
• Oil-based clay
• Duct tape

Instructions

1. Empty out two 2-liter soda bottles, and rinse them out with water. Allow the bottles to dry completely for one hour.

2. Fill one of the soda bottles halfway full of sand. You can find sand at any home improvement or hardware store.

3. Press oil-based clay into the opening of the sand-filled bottle. Cover the hole completely. Repeat this process with the other bottle, covering the hole with the clay.

4. Push a pencil through both clay-filled openings. This will cause the openings to have a pencil-sized hole through them.

5. Place the empty soda bottle on top of the sand-filled one, and line up the openings. Wrap duct tape around the two stacked openings to secure them tightly together. When you flip the bottles upside down, the sand will flow from one bottle into the other like a sand hourglass.
