These little eggheads are an adorable project! Just plant the grass seed and watch the hair grow.
How We Did It
For young kids who might have trouble handling an empty eggshell without breaking it, start with drawing on a face with a permanent marker (washable markers will run when you water your egghead).
This step is for adults only! Using the tip of the knife, poke a hole in the top of the egg, and keep poking it out until it's the size of your fingertip. Using your finger, pull off bits of the shell until the opening is big enough for a good crop of hair.
Dump the raw egg out (may as well make scrambled eggs while you're at it!) and rinse the empty eggshell.
Place your eggshells into an empty egg carton, and place one soil pellet in each. Add in water until the soil has expanded and is nice and moist. (Or just use potting soil.) Sprinkle the grass seeds on top.
Place your eggs in a sunny spot and check the soil daily. Add water if it looks or feels dry. You should see sprouts in a few days.
Trim their hair and enjoy!
