burned for 96 straight years.

So
maybe their website looks like it was designed by the Cyber Dsign Clan, but perhaps
Harris Educational's website is meant to evoke a more simple time in
web design to reflect the retro-gadget science kits they sell,
including the 'Build Your Own Telegraph' kit ("Take Text Messaging to
a Whole New Level!") or the 'Build Your Own Lightbulb' kit that allows
students to create a real, functioning light bulb with a partial
vacuum that burns for up to five minutes. They kits even look the
part, with sturdy wooden bases -- none of that cheap plastic crap for
my son's telegraph -- and metal switches. Although each kit is
sold through a number of different retailers, it looks like each one
rings up between $40 and $65 or so.
Hands on is the best science learning there is. Watching my 7th
Grade science teacher shatter a banana with liquid nitrogen will
always be indelibly frozen into my memory -- he never did explain why
we had to be naked for it to work, though.

Nifty
showerhead has built-in electricity generator.
Water enters the shower head through the flow resrictor
(1) then travels through the injector plate (2) which directs the
water to the waterwheel (3). The water spins the magnetic waterwheel
past the stator (4) of the field wincing (5). This hydroelectric
generator develops the 2.5 volts at .31 amps which lights the PR-6
bulb.
The result? "The Showerstar will be sure to light up your evenings as
the perfect addition to any romantic setting." I doubt it. The kind of
person who would buy one of these would probably prefer taking a
voltmeter into the shower than a partner.
