Why do your feet look like they are attached at a different angle when you're standing in water at the beach? Teach the children with this plastic water prism. Also make rainbows. Measures 8-1/4" x 2" x 1" with 3/8" squares across the surface to measure refraction.

Gray is for grown-ups. This duct tape is made for the young at heart. You’ll get (30) feet of 1-7/8” wide duct tape on a 3” core. You pick: aqua, chain-link fence/skyline, yellow, or translucent white. Instructions for making wallets, purses and more not included.

This political globe (i.e. with country boundaries) measures 11” dia, a tad larger than a standard basketball (which is 9.55” dia), and comes on a 7-1/2” base with latitude marked on its bracket. Shipped in two halves--all you have to do it push them together, although you should also feel free to use the halves as stylish bowls.

These (2) reproduction maps are printed on "antiqued vellum" and are both approx 15-3/4" x 14". They show, respectively, the locations of Civil War battles and the principal events in the Revolutionary War, along with chronologies at the bottom. Lots of info packed into a small space, but the kids will read them easily. You might want some glasses. Includes both maps.

The kind you hang in the front of the laboratory or on the classroom wall, which is what we suggest you do with this one. Measures 38" x 50" and is laminated to protect it from flying students.

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.

Call them the Founding Replicas and display them in the classroom, whether at home or in school. The U.S. Constitution is 18-1/2" x 12-1/2" and the Bill of Rights is 15-5/8" x 13-5/8", both on realistic "antiqued vellum." These are nice replicas, but much reduced in size, the Constitution in particular will require magnification for reading. Our each includes both documents.

This piratical treasure trove is printed on genuine pretend parchment (from a process that involves skinning ersatz sheep). The 15-3/4" x 13-3/4" Treasure Map shows (56) actual lost treasure sites from Newfoundland to Bermuda. Call us when you finish looking. The 11" x 14" Pirates Creed of Ethics (the apostrophe was sunk along with the treasures), is a faux vellum document with a putatively real pirates' code from 1640 with (14) principles, many of which involve getting one's head split for infractions. Both profusely illustrated.

Professor! Professor! A picture’s worth a thousand lectures! Post these funky, full-color cartoon posters in the lab or classroom. The 17” x 11” posters repeat all the things you’ve been telling the students, but — let’s face it, Prof — the posters are way funnier than you are. Our each is a set of multiple posters — (6) different in the set reinforcing scientific methods. Funny for middle school through med school, student lab through working lab.

We've got (2) great grid-posters for the classroom or the lab. The 18" x 24" posters have 1/2" squares, 33 x 27, with headers on the x and y axis. The all-around borders have outer-space images or dinosaurs. Why not get both?
