  • Two empty 8oz water bottles
  • Salt
  • Glue and/or strong tape
  • Cardboard
  • Nail
  • Markers for decoration


  • Let's make our own hourglass to use as a timer!
  • First, I’ll use a nail to make a hole right in the middle of each bottle cap. Then, let’s stick the caps together with glue. The tops should touch each other.
  • Now, let’s pour salt into one water bottle, and screw two back-to-back caps on. Then, let’s screw the empty water bottle onto the other cap. When everything is attached, let’s use strong tape around the necks of each bottle and the caps to keep the hourglass stable.
  • Let's glue cardboard squares to the bottom of each bottle for stability … and decorate our creation.
  • Now we can turn our hourglass over and watch the salt fall from the top to the bottom. How long does it take for all of the salt to fall from the top bottle to the bottom empty bottle?
