Solar Battery Charger
Convert solar energy to electrical energy and store in your own batteries. Charge
your rechargeable batteries anywhere the sun shines. Solar Powered Battery Charger
recharges Ni-Cd or Ni-MH AAA, AA, C, or D cells, 2 at a time. Rechargeable batteries
are not included, but are commonly available. Excellent for wilderness camping.
Also called the "Solar 11-in-one Battery Charger with Meter".
SOLR.11 $29.95
Radiometer
This has got to be the coolest science toy around! A clear glass bulb, partially
evacuated, contains 4 vanes or wings balanced on a virtually frictionless pin bearing.
The vanes are black on one side, white on the other. When placed in sunlight
or under a bright incandescent lamp, the vanes will spin around. The brighter the
light, the faster the vanes will spin. Very fragile, for ages 12+.
SOLR.08 $19.95 each
Sunprint Paper
Also known as "solargraphics paper". Make sun print images without a
camera! Sunprint paper goes through a chemical change when exposed to light.
Use the solar graphic paper on a sunny day, either outside or on a sunny windowsill
(even works on some overcast days - experiment to find out). Here's how it works: In
a dimly-lit room, place any object that casts a shadow like a tree leaf, a fern leaf,
confetti, a photographic negative (OK, in this age of digital photography, you kids may
not even know what that is! - ask your parents if they have any), etc. on the blue,
light-sensitive paper. Cover with the clear acrylic sheet that comes with the full
kit. Take this assembly outside and place it on a solid surface where it is exposed
to the sun. Leave it alone for 1 to 5 minutes (depending on the strength of the
sunlight), until the paper turns almost white. Without moving the object off the
paper, quickly bring the assembly back into the dimly-lit room, take the exposed paper and
rinse in water for about 1 minute. Dry flat. What you will have is a preserved
image of the shadow of the object. For ages 6+.

UV Beads
This is a fun and creative way to detect and demonstrate the effects of ultraviolet (UV)
radiation (the component of sunshine that causes sunburns) that comes from the sun.
When these small plastic pony beads are exposed to sunlight, even on cloudy days,
they change from white to colours. Out of the sunlight, they turn back to white.
Regular light bulbs (incandescent and flourescent) will not affect them because
they lack UV radiation. For a science fair project (i.e. which sunblock is more
effective?) put sunscreen on a bead and you can see the UV blocking effect.
Experiment with materials that supposedly block UV rays (sunscreen, sunglasses,
tinted glass, etc.). Use for craft necklaces/bracelets, party favours, as well as
discussion of non-visible wavelengths of radiation, or just for fun. Can cycle from
white to colour and back again over 50,000 times. For ages 6+.
SOLR.16 Ultraviolet Beads, package of approx. 100, mixed colours

Black Light
Hand-held portable blacklight (ultraviolet light) set, 12 inch (30.5 cm) bulb and fixture.
Power with 12 volt cigarette lighter adapter (included) or use 8 AA batteries.
Works well to detect Glo-Germ Powder (see below) or at funky parties. For
ages 12+.
MISC.80 $15.95 each
Glo Germ Powder
Non-toxic white powder glows under ultraviolet light. "Simulated germs"
used by heath nurses and lab trainers to safely demonstrate proper cleaning or
disinfecting methods. Sprinkle or smear a bit of Glow Germ powder on the surface to
be tested (you don't have to use much - a little goes a long way). Test with UV
light source to show where the powder is (Black Light sold above works well), then clean
surface by whatever method you choose. Re-test with UV light source to see how good
your cleaning practice is.
