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.

Speak Up
Gold-plated contacts - what everybody needs to do business today. But in this case, they're part of our 1" dia, 150 ohms mini-speaker. Drawing less than 1/4 watt, this is the type of speaker used in cellular phones, and has good sound quality if held close to your ear. The peel-away adhesive mount makes it a great component for a small project. They come (2) to a package, so think small stereo.

Mirage Maker
Absolutely incredible device! The Mirage®, a precision optical instrument, creates three-dimensional images of objects of your choice where there is nothing. Drop pennies, keys or similar small objects (your sister won't fit) into the 2-3/8" dia opening of this 9" dia x 3" high flying-saucer-shaped disc, and a perfect image of the object will appear floating above it. The image is so real friends will try to grasp it, but their fingers will close on thin air! Use it as a high-tech centerpiece with a flower as the object! A booklet (included) explains the magic. New coating provides protection for the mirror surfaces. Highly recommended. Made in the USA.

Puff the Magic AirZooka
Mega-cool toy air cannon. Birthdays will never be the same! The instructions on the AirZooka" say it blasts a gust (ball?) of air up to 20 feet but we blew out a candle at 30 feet, and it only took us three tries. (And you can hear the near-misses as they blow past--which is the mega-cool part.) Plastic, 11" dia x 10 1/2" deep, like a bucket with a pistol grip and a fold-down sight. The (3) segments unscrew and collapse for storage between birthdays. We'll pick fluorescent blue, green, magenta or orange, and you'll need two if you want to have air wars.

Butane Beauty
It's stylish, it's handy, it has a slightly menacing look to it, and-truth be told-it's a lot of fun. It's a handheld butane torch, great for everyone: in the lab, under the hood, working with circuitry, melting copper and other metals; heck, a chef can even use it to flambé the dessert. 6-1/4" tall, 3-5/8" x 2-1/4" dia base, 3-5/8" long at the top, with a textured grip, push-button start with safety, and air adjustment to control the size of the flame. Easy to fill with butane, which you'll need to do 'cause no fuel is included.
