Make an Hour Glass Timer

You will need:

• 2 x empty soda bottles with lids
• Fine sand (enough to fill each bottle halfway)
• Strong tape
• Scissors

STEP 1

• Make sure each bottle is clean and dry.
• Fill one bottle halfway with fine sand.

STEP 2

Cut a hole in the top of both plastic lids. Make sure these holes are similar in size and shape. For younger children, prepare these ahead of time, as the hard plastic lids are difficult to cut.

STEP 3

• Place the lid back onto both bottles.
• Rest one bottle upside down on top of the other, making sure the lids match up neatly and the holes are level.
• Tip your hourglass timer over to ensure the sand runs freely from one bottle to the other with no leaks.
• Tape both bottle’s lids together.
