Simple Hourglass Using Recycle Soda Bottles

Hi All,

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.

Material
- Two soda bottles
- cello tape
- Cutter
- PVC solvent
- Sand

Cut the bottles from top and bottom as shown and fix them with transparent tape

The sand should free flowing. Dry it in Sun if needed.

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.....

Use small acrylic sheet with 3mm hole at the center

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


Tips:
- Wash sand for dust
- Use narrow soda bottles
- Adjust sand depending on desired time
