Brain Benders
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A box of illusions: make big objects look small, and small objects look big; change black and white into color; turn drawings into old-style movies - just for starters. You get a motorized zoetrope/spinner with discs and strips, and a really amazing "altered perspective chamber," along with directions for a dozen optical activities. It's really mind-bending - but don't forget to buy (2) "AA" batteries for the zoetrope. Spinning it by hand just doesn't work as well! For ages 8 to adult.
