Chemicals Make a See-Through Mouse

Want to see something cool and kind of gross? Check out the photo of an invisible mouse at AAAS's Science Now site. Okay, the mouse isn't actually invisible (or else you wouldn't be able to see it), but it does have ninja-mouse transparency. How did this happen? Scientists knew a mixture of soap, glycerol and urea rendered synthetic membranes transparent, so they applied the mixture to natural tissue to see what would happen. The result was that the pigment cells in the test subject were rendered invisible, making the entire organism see-through. You mixture is too strong to be used on living organisms, so if you want to become invisible you'll need to try something else.
