Question

how to make a ancient water clock

Answer 1

Supplies you will need-

2 water bottles
Coffee straw/stirrer
Hot glue gun
Sharpie marker
Drill
Timer

Empty the water bottles and keep the lids. Using a hot glue gun, glue the tops of the two lids together.
Find  drill bit to match the width of your straw and drill two holes through the two caps.
Cut the straw in half and place them through the holes with one long and one short facing each side. Trim off the extra. And hot glue around the edges of the straw to secure them in place.
Fill one bottle with water and screw the lids back on to both bottles.
Flip the bottle and time the water. Mark with a line at each minute. Flip and do the same on the other bottle so both sides have the minutes marked.
The water clock can be used as a regular timer for games or activities.  Add colored water to make it more interesting! My kids have been totally obsessed with this since I made it!
