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.

It's nice to know that some things don't change. One is the Jacob's Ladder. Still made with (6) slabs of wood, each about 2" x 2" x 1/2", each a bright combination of colors, and all connected by a contrasting ribbon. Hold one end up and let the string of slabs dangle. When you flop the top block end for end, each lower slab in turn will flop end for end. Fascinating. Particularly if you are about 5 to 9 years old.

Y columna vertebral. Y the bones, fractures and dislocations associated with them. All the text on these 26” x 20” slightly glossy anatomical charts featuring the shoulder, elbow and spinal column is in Spanish. If you want them for a classroom or a doctor’s office, better get them fast, before they sell out as funky wall art.

Think of it as a shortcut to learning perspective. This clever 50-sheet pad of white, 7" x 4-1/2" paper has a fine red and blue grid pattern that shows your drawing and doodling in 3-D when you wear the included 3-D glasses. It's our candidate for the why-didn't-I-think-of-that award this year.
