Đồng hồ cát toilet (Toilet sand clock timer)

Toilet sand clock timer

This is my custom version of sand clock from  https://katamco.com

Carpe diem is a Latin aphorism, usually translated as "pluck the day" or "spend your day trully"

Assembling

Cover the empty holes with a transparent adhesive tape or thin plastic foil.

You can use sand or table salt to fill back-box. Both salt or sand must be absolutely dry. To be sure, we will also insert and glue the silicate gel inside.

The sift time depends on both the particle size and the size of the hole. On the down left picture is table salt and on the right is  synthetic glass ceramic powder. You have to experiment.

At the finish glue cover and back-box together.

Have a fun !
