Scientific cookie round-ups
A couple of killer round-ups of science-themed cookies.

DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!
Experimenting with Cuprous Oxide diodes
Pete Friedrichs, author of the can’t-be-recommended-highly-enough Voice of the Crystal and Instruments of Amplification (which I review in MAKE Volume 21), has posted online his two-part article “Fun With Homebrew Cuprous Oxide Diodes,” which originally appeared in the Xtal Set Society Newsletter. In it, he shows you how to build an old-school Cuprous Oxide-based radio […]

Soaps that look like Petri dish cultures
This week’s clever maker-entrepreneur award goes to Etsy seller Cleaner Science, who makes and sells these awesome soaps that look like petri dishes full of growing germs.

Fiction science: Aliens, Predator, and Mega Shark infographics
The second graphic explains the physics behind what Boing-Boinger Jimmy Guterman has described as “the greatest scene ever in the greatest movie of all time,” viz. the destruction of a cruising jetliner by the eponymous “Mega Shark” from Mega Shark vs. Giant Octopus. You may be interested to know, for instance, that Mega Shark’s air attack requires that it break the surface of the water with a velocity of 710 km/hr, which is faster than a bullet train but not quite so fast as a Tomahawk missile.
Giant pile of scrap gears
Just this morning Cory Doctorow blogged this snapshot, taken by one “Joel,” of an ancient gear burial ground at a scrapyard near Charlotte, NC. I wonder how many wild-eyed steampunks they’ve had come sniffing around since then. [via Boing Boing]
Guitar Slide from a Wine Bottle
One interesting historical example of upcycled crafting is bottleneck guitar– or as it is now widely known, slide guitar. The unique resonant sound of slide guitar was originally formed by playing with a glass bottleneck over one finger and running the slide up and down the strings. While the materials for making slides have evolved, […]
