Agar, it's not just a crossword puzzle answer. It's the medium of choice for growing bacteria, molds, etc., and just what you need if you're shopping for laboratory staples or for your next science-fair project. Melt the medium in a microwave, pour into a Petri dish, and allow to set before applying test material. Do not freeze, and after exposure or melting, store at the temperature on the label. Does approx. 10-12 petri dishes.

For fun or science. And it's not actually smoke, but a fog created the same way they do for movies and heavy metal concerts. The Zero Blaster is a ray-gun-shaped, black-light-sensitive pistol that pumps out 2" to 4" dia smoke rings (rotating toroidal vortices, to be exact) that will, one after another, waft up to 12 feet away for hours of good, clean fun. Measures 9" long x 6-1/2" high. The Wizard Stick is a fog-producing wand, 10" long on a 4-5/8" x 2-1/4" base, and comes with an instruction manual for science experiments and special effects, including making wind tunnels and a vapor-ring blaster. Also good as a household draft-finder. Each takes (6) "AA" batteries, not included, and comes with a 3-ounce bottle of non-toxic fog juice, good for 25,000 smoke rings or a whole lot of fog. Better order an extra bottle of Super Zero Fluid, the replacement juice, just in case.
