Grow a beautiful garden full of plants that love your soil! It's easy if you know your soil's pH, and we have a gauge to help you! Stick the probe into moist soil for the pH to register in a separate 4" x 2" x 1" gauge box on the end of a 26 inch cord. That lets you read the gauge without having to lay on the bug and worm covered ground to see it! A needle indicates the pH on a scale of 3.5-9, and you get a list of which plants like which pH levels.
Even as we speak, there are nefarious techno-thieves on the streets ready to read the personal data on the RFID (Radio Frequency IDentification) chips in your wallet. Foil them, we say, foil them with these RFID shields. You pick either the 6-1/4" x 2-3/4" sheet to slip into your wallet and fold around your cards, IDs and passes, or the 3-pack of credit-card sized sleeves, 3-1/2" x 2-1/4". Or both. Made in the USA.
Twelve-year old Tommy is a whiz with kits and models—but who knows which
one he wants? Tommy’s teacher creates great art and craft projects—but
who knows what off-the-wall materials will inspire her? And Grandpa Sam!
Who knows what motors or bearings or resistors or piezo speakers he
wants? Or what in tarnation he wants them for? Doesn’t matter! Give them
all gift certificates! Just select whatever combination adds up to the

More goose-sized than chicken-sized at 3-3/4" tall x 2-3/4" max dia, this soft, translucent-rubber egg glows with color. It can be set to stay one hue, or to change very slowly from purple through blue, green, orange and red to purple…. Very Zen. Or very cute in an Easter basket. Runs on (3) replaceable button-cell batteries, included.
I am not a rock, I just look like one. I'm actually a 3-1/2" x 2" x 1-1/2" deceptively rock-like hunk of gray and black polyresin that's hollowed out to hold your spare key and hide among all the other rocks.
Our laser combo pack scores you two pen-shaped
5mW laser pointers, (1) each in stopping red and going green. These colors are
also perfect for Christmas, St. Patrick's Day and St. Valentine's Day. Oh, and
nautical situations. The housing is flat black or silver with a gold pocket
clip and head. The 532nm Class IIIa green light is 5-5/8" long x 1/2"
dia, with a momentary-on switch. It's brighter than the red so it's perfect for
all daytime pointer needs. The red is 5-1/4" long, and its mellow red
light makes it more suitable for board room presentations but we've thrown ours
two blocks at night, no problem. Green or red, whatever you do, don't cross the
streams. Each pointer takes (2) "AAA" batteries, which are included.
Our motion-activated dispenser will take liquid soap or hand sanitizer and pour either into your hand without you ever having to touch anything. Stands 7-1/4" tall x 2-1/2" dia in stainless steel on a waterproof stand. Holds 8 oz, is easy to fill and if you like to touch stuff it also has a manual trigger. You add (4) "AAA" batteries.
Hook these on the zipper pulls on your jackets and you'll never be in the dark again. Tiny LED lights measure 1" x 9/16" in a 5/16" thick oblong, and come on a 7/8" long lanyard clip. We'll pick some that will go with your eyes, in blue, green, black or red. Include little button cell batteries that can be replaced if you're the sort of person who does that.
