Students use all five senses to create their own candy. Also, creativity will play a major role in this activity. I recommend using this worksheet after reading Chapter 19 (we get a good description of a few of Wonka's inventions).
Great for special and general education students.
As for special/unique aspects, my students thought up ideas like: you're skin will turn into the color of a rainbow, my candy will give you superpowers, you will become invincible, etc. etc.
