Carve a funny face into an apple.
First draw the face onto the apple with a felt tip pen. Make it funny or scary, or happy. Then use a fine tipped pocket knife to cut out the shapes of the face. Voila! These can be put on a ledge to dry and over time they will become even funnier.
Boil the apples first to make them softer to carve into. Let them dry and then draw your funny face onto the apple with a felt pen. Do not use a pocket knife. The knife should be blunt so that children will not hurt themselves while carving.
