Love Meter

AKA hand boiler. An exotic bit of hand blown glass with a bulb at top and bottom connected by some zippy tubing that spirals, loops, and/or jogs. In the closed system is some colored liquid (methyl chloride) that is very light. Hold the lower bulb in you hand and as the air in the system is warmed it pushes the fluid through the loops to the upper chamber. When all the liquid is pushed out of the lower bulb, expanding air will bubble through the tubing making it appear that the liquid is boiling. WARNING! The glass is fragile and the liquid is nasty. If you drop the thing on e.g. the kitchen tile, it will eat the finish off the tile and the stain in the liquid will permanently stain the floor. So don't let kids handle this item unsupervised. About 7" tall, it is a favorite in our stores.

3-D Specs

You remember: white cardboard frames with red and blue plastic lenses. The temples fold to 5" long. 3-D's a lot more fun in these days of the Web: go to www.howstuffworks.com for binocular disparity and rivalry tests, or just Google around to find fun stuff or school optics experiments to use these with.

A Working Wonder

If we had a category just for customers who lust after Jules Verne inventions and elegant gadgetry, this would be in it. The wonderful brass sundial, a reproduction of an antique, is approx 3" dia x 11/16" thick overall, and actually works! A latitudinal gauge lets you tilt the engraved dial to the correct angle for your location, and a bubble and three leveling feet allow the 1-1/2" dia lock-down compass to point in the precise direction. And if you never took it out into the sunshine, you'd still love it for the look and logic of it.

Almost Real

And close enough, because sometimes the threat of security will do. Our simulacamera looks like the real thing, even though it isn't, with an activation light and a quite real motion detector that causes the "camera" to pan from side to side. The unit measures 3-3/4" x 2" x 2" with a 1-1/4" dia lens. It's mounted on an adjustable 4" x 1-1/8" x 3/4" arm attached to 3-1/8" dia baseplate with (2) 3/16" mounting holes. The angle adjusts from 45 to 180 degrees, and the motion detector starts the head swinging 20 degrees in either direction for approx (15) seconds. Takes (2) "AA" batteries, not included, but does include mounting screws and mollies-and a tiny, tiny price.
