Question

Something that might involve optical illusions, or biology, or light, or SOMETHING like that! Please answer ASAP!

Answer 1

M.C.Escher was a graphic artist that drew some of the more intreging optical illusions ever. Have a look the web site I found of his work.
The first is the home page
2nd is "Drawing Hands"
3rd in the impossible "Waterfall"

There is so much to do but I will let you decide

Update:

M.C.Escher is cool, I know the a guy that holds the right to M.C.Escher art, in Norwalk Connecticut if you ever in area go there you can see pieces that will blow anyone away.

Back to project:
How about standing in front of mirror reflect light off you so the mirror pick's you up very clear, then align a piece of glass in a hallway to pick-up reflection, move around to make ghostly image.

Never mind that a big project for 6th grad and you would need partner
