You are What You Eat!
What you eat becomes you.  Literally.  Think about the snacks you choose- what do they say about your personality?  Are you sweet-tart?  Salty? A hot fry?  A kiss or a cry-baby?  Can you skittle?

Students kept a food diary and discussed the role junk-food plays in their life.  They created a cast plaster mask of their face, and used their favorite snacks to illustrate their personality.  This created an awareness of their relationship with food while providing the sculptural experience of casting with assemblage.

Aren't they sweet?
