Experiments in Future Technics
Thames & Kosmos® offers Power House, an extraordinary introduction to regenerative energy sources and sustainable living. Young scientists age 12 and up use the components of the kit to build a model house and (20) other energy-related devices, learning about energy from the sun, wind, plants, and electrochemical reactions. Along the way, they cook a potato with sunlight, make fresh water from salt water, galvanize a nail and split water into hydrogen and oxygen, and much more. The 96-page, full-color manual integrates experiments and activities with an engaging story line. The kit carries The National Parenting Center Seal of Approval, and is the winner of a Preferred Choice Award from Creative Child Magazine. Very, very nice.

Laser Pointer Par Excellence!
Da Mare could use this to point out cracks in the infrastructure at Wrigley Field. You, having a forgiving nature, will resist the urge to point out cracks in da mayor's infrastructure. You will, of course, use it to point out chimney cracks to the tuck-pointer, a cracked limb to the tree-trimmer, and the crack in your profit picture during a slide presentation. You can do all that and much, much more with the bright light from this chrome-plated, 5mW green laser pointer. It's an unbelievable tool. If you need a laser pointer that seems to go on forever and is so strong that you can actually see the beam in the dark, it will be the best low-cost investment you ever made. Or the coolest high-end toy. The 532nm Class IIIa light is 5-5/8" long x 1/2" dia, with (2) "AAA" batteries (included), a momentary-on switch, pocket clip, and padded wooden carrying case. An absolute necessity for construction, surveying, warehousing, inspection and other large sites. And for playing in the dark.
