“Have a Nut” Sailboat

Materials

Walnut shell
Leaf
Twig
Clay
Instructions
1.For each, you’ll need an intact half of a walnut shell (see our tip below).

2.Thread a leaf onto a twig for a mast and a sail. Secure the mast to the inside of the shell with a small ball of clay.

Tips:To open a walnut without breaking the shell (an adult’s job), hold it steady on a cutting board, insert the tip of a flathead screwdriver or a butter knife into the flat end of the seam, and carefully pry the halves apart.
