Put Sunnytech's Stirling-engine contraption on top of your morning mug of hot coffee, and watch it whirl and hear it clink. When it stops, you'll know your beverage has reached a pleasing drinking temperature.
This think piece, developed by veteran workplace creativity consultant Roger von Oech is a 30-sided polyhedron that's assembled from 30 tiny magnetic pyramids and can be reassembled in almost any way you can, well, think of.
Crazy Aaron's specializes in what it calls thinking putty. We like Crazy Aaron's Strange Attractor variety because, one, it's magnetic, two, it comes with a magnet, three, the magnet makes the putty sparkle, and four, we just know it'll make us the talk of the office.
Take iron-rich fluid, put it in a bottle, add two magnets to the outside of the bottle and what do you get? Peaks and patterns reminiscent of the black oil on The X-Files, all courtesy Mokiki's bottled ferrofluid.
