You'll never lose your chance to highlight something when you hang your highlighter around your neck. These have a 3/16" wedge tip (every true highlighter's choice), and come with a pocket clip and a detachable 18" lanyard. You pick yellow or pink.

This 6" x 8", 50-sheet ruled notepad mimics an iTablet screen, to make you more comfortable writing on actual paper. (Use a pencil, the original stylus.) As a bonus, it has a magnetic strip on the back so you can stick it on the fridge, which you shouldn't try with your tablet.

If the question is whether to tie a bunch of these giant latex professional weather balloons to a lawn chair, the answer is no. (The balloon bursts at about 82,000 feet anyway.) This is a true high altitude weather balloon, with plenty of fun, nonfatal uses. The cream-colored latex balloon is approx 60" dia when flaccid, you should pardon the expression, but has an 14-foot dia when inflated. The neck is 9" long x 3" dia. Scientists and meteorologists launch balloons to measure atmospheric conditions like wind speed and air pressure for weather forecasting, but clever inventors, teachers and the imaginative filmmaker are warned to launch the balloon carefully. The synthetic rubber material is delicate and not made to survive brushes with pavement, pine branches, or clumsy physics students. Have fun, and launch safely.

When we were your age, our protractors were all just plain clear plastic. You kids today can get them in translucent blue, red, orange, purple or green, but we're going to pick because we didn't get to then. These pretty ones are 6" wide and read from 0-6" x 1/16" on the bottom and from 0-180 degrees x 0.5-degrees bidirectionally along the arc. Include holes for a 3-ring binder.

You can write on duct tape, but try to change your mind later and see what happens. We recommend these 12-foot x 1-7/8” wide rolls of dark gray chalkboard tape, which you can write on with, you guessed it, chalk; or the 12-foot rolls of the more modern dry-erase tape, which we’ll pick for you in either white or day-glo orange.

This rubber disc magnet attracts to the tune of about 1/2 lb. Measures 1-11/16" dia x 1/8" thick, with a London-Tube-Sign-shaped 21/32" slotted bore. It's 8-pole, made of bonded strontium ferrite.

A must-have for micro-warriors; Mini Weapons of Mass Destruction by John Austin (author of the best-selling Cubicle Warfare) is 241 pages of detailed instructions for building (42) implements of spitball warfare from ordinary household objects and office supplies. With the caveat that this is written for responsible individuals who take reasonable safety precautions (don't do anything your mother would scream at) we have to say that we love the binder-clip crossbow and the tongue-depressor catapult. Volume 2, which is 251 pages, has a secret-agent flair with new gadgets like the push-pin dart, toothpaste periscope and cereal briefcase. Volume 3, 267 pages, continues with a Medieval flavor and over a dozen catapults and ballistae, plus a buncha bows and crossbows. Oh, just buy the whole 3-volume Library of Destruction and get it over with.

Y columna vertebral. Y the bones, fractures and dislocations associated with them. All the text on these 26” x 20” slightly glossy anatomical charts featuring the shoulder, elbow and spinal column is in Spanish. If you want them for a classroom or a doctor’s office, better get them fast, before they sell out as funky wall art.

A stylistic cartoon cutout (dog, cat, bear or pig) folds its head and its feet (paws?) over a school picture or signature. Kids too young to write much will be giggly over the heartfelt Valentine messages, like the pink pig who says "HOG WILD OVER YOU," the red dog who says "I WUFF YOU," etc. You get (6) of each type, for a total of (24) in your order. Goofy cute.

Cheaper -- a whole lot cheaper -- than hiring a guide, plus these fit in your pocket (which is only true of the tiniest human guides). These hunting and fishing helpers are written and illustrated by professionals and are dense with information and step-by-step, full-color instructions for deer and duck hunters and fisherpersons. They're printed on heavy laminated 8-1/2" x 11" stock folded to a pocket-sized 4-1/4" x 5-1/2". The series includes how to site and work a deer stand; cast for and trigger bass; and how to work with minnow rigs -- which is always a plus. Original retail price of each was $4.95.

These tiny alnico magnets are a mere 3/8" long x 1/8" dia cylinders, slightly larger than ice-cream jimmies, with approx 1/4-oz lift. They could hold sticky notes that have lost their sticky, and they hang on to each other end-to-end really nicely, so a bunch of them are fun to play with as a desktop toy, but they're really great for magnetic reed switches. Sold in packages of (25) or try the (200) pack for huge savings!

This 96pp, full-color, heavily illustrated book, "The Usborne Internet-Linked Book of Astronomy & Space," is written with a quick-link to the publisher's website, where there are updated links to internet sites that correspond to specific pages of the text.

All you add is sunlight to use this 50-foot long solar balloon to prove that Bernoulli was right. Pascal, too. Demonstrate buoyancy, convection, thermodynamics and the power of the sun. Measures 29" dia and comes with 400 feet of string, and instructions.

Dominoes aren't just for those old guys with cigars in the park. These use Cuisenaire rods to help teach basic math concepts.

Shiny! This plated rare-earth magnet is 3/4" dia x 1/8" thick and has a 6-lb pull. Ignore the 12-lb rating on the box--that's why you're getting this so cheap, and 6-lb is plenty of pull for one person anyway.
