Walnut Shell Boats

Winter is a great time to create some sailboats for a warm bath after playing outside in the cold winter weather.

This time of year, whole nuts are widely available.
Purchase some whole walnuts, along with pecans, almonds, and hazelnuts from your produce department. Shelling nuts is a great science activity because it's not often children see the nuts prior to being shelled.

You will need:
whole walnuts
pool noodle or other type of floating, waterproof foam
toothpicks
plastic lids
scissors

• Keep the walnut shells you are able to keep together as a half.
• Cut small pieces of pool noodle foam to fit into the walnut shells.
• Cut narrow (isosceles) triangles out of your plastic lids.

• We used an awl from a leatherman tool to create two holes in our triangle on the long vertical side. Insert toothpick as shown.
• Post your toothpick sail in the foam and set sail!
