See psychedelic patterns the safe way! Press your hand on this 6" x 6" sheet of liquid crystal and leave a print of swirling colors that, like the mood ring of yore, you can use as a sign of your mood. The pattern will blend and fade in seconds as the crystals react to temperature. Tiny liquid crystals inside the film-like material react to heat, 25-30°C (77-86°F) by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut it into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.
And people won't crash into you, because nothing says safety like this high-quality reflective tape, the same material that's used to make stop signs. You get (4) glossy, self-adhesive red reflective tapes, 12" long x 3/4" wide. We're thinking bike fenders and helmets, dog collars, garage door frames, anything that could benefit from a heightened visibility.
Much neater and easier not to cut those monster sheets of foam-core into manageable sizes by yourself. Just order the 9" x 12" size! You get a package of (5), each 3/16" thick. We're thinking a little light model-making, school projects, crafting, photo mounting, lesser bulletin boards, like that.
These here are made for repairing tents after critters tried to get inside or somebody bent over too fast with a machete in his belt. Iron these off-white canvas strips, shiny side down, over the hole and yer tent's like new, almost. Pants too, if ya got off-white canvas britches. Make good iron-on name tags, no matter how short or long your name is. Small are 2" x 2" and the medium are 4" x 2",. Sold in large quantities, in case you have particularly aggressive critters, or an extra-long machete.
Could be a box of squashed geckos, but in fact it's a box of (20) huge self-adhesive labels, 10-7/8" x 8-1/2", in an alarming neon green. Good for printing, but equally good for writing very noticeable notices on.
Unused X-ray film is the cut-out and stencil material of choice for airbrush artists, plus the colors (nicely muted grays, browns and greens) are screaming to be art and craft supplies, sign stock, placemats, or model fodder. You get (8) sheets in sizes ranging from 8" x 10" up to 14" x 17". Some may have vague shapes of smaller sheets very lightly burned into them if you hold them up to the light. Sorry, no leftover X-rays included.
Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.
Make your own sparkling magnets with our flexible, cut-able 8-1/2" x 11" sheet of 1/32" thick magnetic rubber. The silver glitter finish under a diffraction layer creates mesmerizing rainbow effects. You'll get (3) sheets of magic glitteration to play with.
