The instructions recommend this kit for experimenters nine years old and up, with adult supervision.

Our aluminum canisters with clear glass pull–off lids are cool. When a set of a dozen contains lavender, red and 10 other colors, it’s cool to the max. The smallest canisters are aluminum–colored, a set of (20) 1–1/4” dia x 3/4” deep in a 6–1/2” x 5–1/4” x 7/8” lightweight aluminum box with a hinged lid. When the box is shut, a layer of foam padding inside the lid presses down on the canisters, keeping them securely closed. An ideal carrying case for paints, many different screws, or other sets of small items or quantities that must remain separate. If you need slightly larger canisters, and a cardboard box will work instead of a carrying case, try our colorful display, anodized tins in great colors come in a set of (12) 2” dia x 7/8” deep. Prices are per set.

Add a little pizazz to your nitro pills! This 1-3/4" x 1/2" dia container for meds is anodized aluminum in mostly silver but also could be in blue, turquoise, purple, red, gold (our choice). It's gasketed so it's watertight. We recommend cleaning the inside with a cotton swab dipped in alcohol before using, since some have a bit of rust-colored residue in them. Flashy!

Let's cut to the chase here -- buy these the first time you read this, or they're going to be gone!

Our each is a set of (2) of the translucent Euro-look mats that protect countertops from sharp knives and fresh-from-the-oven cookies, and protect food from outdoor surfaces.

This deluxe ABS storage case is called a Store-It-ALL, and it does. But it could be called a Carry-It-ALL, for the sturdy handle and locking clasp, or it could be called a See-It-ALL, for its translucent lid. Or a Fits-It-ALL, for the removable dividers that let you configure it with any number of compartments from 5 to 26. But the 12" x 18" x 3" OA case should really be called ALL-I-Ever-Needed- To-Get-Organized!

They come in an assortment of five colors with two leads in each color. The manufacturer calls them heavy duty but we would restrict them to the light currents and low voltages you will be using in your home experiments. Our each is a set of (10).

With cord. You'd think it would be easier to lose the tent stakes than the tent itself, but that's apparently what happened here. These are a set of (6) 10" long x 1/2" dia tubular aluminum stakes, cut at a 45° angle on the bottom and with holes drilled in the top. Includes (54) feet of 1/8" dia white nylon cord threaded through the stakes, but easily removable. Perfect if you're in the majority of folks who remember your tent when you leave the campground but don't remember the stakes.

They're fightin' over this stuff in the office. The 3M" people call it "Bundling Wrap" and sell it for wrapping fishing rods, bundling tent stakes, cable, cords, like that, but we think it's got hundreds of applications. It's 1" wide forest green fabric ribbon/tape with very, very small hooks on the back and teensy loops on the fabric front. Cut off just the amount you'll need, wrap it around stuff, and it hangs on like it's in love. Very useful for gardening, crafts, organizing tools and briefcases, strapping pants to ankles on bike commutes, being the utilitarian ribbon on a gift wrapped for some handy guy, and lots more. You'll get a 9-foot spool, super-cheap, and we'd hide it if we were you.
