We used to love doing this with our girls....making egg-heads.
1 egg with the inside blown out
plastic google eyes
grass seed (herb seeds work to)
a red permanent marker
Give the egg head a hole on the top off it's head
We then place a cotton ball in the hole that we made, put a little grass seed on the cotton ball and water....next decorate the face with eyes and a mouth. We cut our egg carton and place the egg-head in one section of the carton. Place in a sunny window....their hair will start growing in a few days....make sure your children keep the cotton ball watered with the spray bottle....and don't forget to give them a haircut when needed.
