In this instructions I will be sharing how to make a simple hourglass by recycling soda bottles.
With things one can find easily at home.
Step 1: What Do We Need ?
- Two soda bottles
- cello tape
- PVC solvent
Step 2: Bottle Preparation
Step 3: Choosing Sand
I stay far from beach so used Quartz sand.
We have to filter the sand using fine net filter. Use the sand that could not pass through the filter.
The fine sand stops in between.....
Step 4: Assembly
Stick it to the mouth of one bottle using PVC solvent
Fill sand in the other and then stick it to the other half
Enjoy your hourglass. time it. Mine is 1minute and 26 sec
- Wash sand for dust
- Use narrow soda bottles
- Adjust sand depending on desired time
