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!
Here’s what looks like a great, culturally sensitive way to tear down old buildings. D-Build, a project started in Syracuse, NY, is aiming to document and catalog entire decommissioned buildings as they are taken apart.
No photos yet. That’s a homework assignment for the bubble chemists in the audience. But I couldn’t resist sharing my excitement over this paragraph from US patent 5246631 for glowing soap bubbles:
An example of practice of the present invention involves using a liquid dish such as LEMON JOY available from Procter & Gamble Company (Cincinnati, Ohio). Although the LEMON JOY may be diluted with varying amounts of water, it is preferred that the dishwashing liquid be used at full strength. Approximately 9 milliliters of CYALUME solution made in accordance with the manufacturers instructions are added to approximately 120 milliliters of the dishwashing liquid. Although this particular mixture may be used to produce adequate self-illuminated bubbles, it is preferred that 3 to 4 drops of glycerin be added to the solution as a bubble hardener. The solution is then ready for use to form self-illuminated bubbles.
I’ve never actually measured how much Cyalume (wikipedia) is in a standard glow-stick, but I’m betting you could come up with 9 mL of the stuff by cutting open two or three at most.
Must. Resist. Yakov Smirnoff. Joke. This is a war memorial, after all, and to a particularly nasty bit of a particularly nasty war, at that. Still, in the same way that Italians can laugh about the fact that, yes, it can be a bit of a pain to renew your driver’s license in Italy, or that Estadounidenses can admit that, yes, we have been known to occasionally over-commercialize certain things, even patriotic Russians will see that there is something of the stereotypically Russian in this story.
This memorial was erected in Ukraine shortly after WWII to commemorate the legions of fallen dead. For 50 years its eternal flame burned natural gas piped in under the Soviet administration. Then…well, things fall apart, as everyone knows. With the breakup of the USSR, the flow of free natural gas into Ukraine stopped and it became too expensive to keep the torch lit. I’m sure it was a sad day that finally saw the flame go out.
Apparently it sat unlit for several years until this compromise solution was achieved: The flame would be converted into a cell-phone tower, the transceivers concealed by a round facade bearing a pixelated flickering LED-flame image funded by the cell-phone company. One of those capitalistic solutions where everyone wins, but only kind of.
To my eye, this is in awful taste. But the story, I think, is kind of beautiful. If it’s really true that the only two alternatives were to leave the flame unlit or to replace it with a cheesy simulation, I think, ultimately, that I would have made the same choice. And as we continue to oxidize the world’s supply of hydrocarbons, sooner or later the sensibility of keeping fossil-fuel flames burning “eternally,” only for symbolic purposes, may well become an issue in other parts of the world.
As for the “paradox,” well, it boils down to this: the three apparently-identical stacked gears on the end are driven by a single gear, yet move at different rates, which, of course, would be impossible if they were truly identical. News flash: They’re not. But I’m sure it was harder to fight boredom in the 18th century than it is now, and the build is undeniably gorgeous.
To “shoot,” an anvil, for the record, is to blast it several hundred feet into the air using a charge of black powder. This delightful man, Gay Wilkinson, is apparently the world’s champion anvil-shooter. The fireworks start at 1:30. [via Boing Boing]
Wondering what all that strange stuff is in your DIY chemistry lab? Well, then you should definitely watch this lab safety video by the The Sounds of Science!
Jim Stogdill sent this to the O’Reilly Radar mailing list: I caught this on 60 Minutes the other night and it struck me as the ultimate MAKE challenge. Guy designs his own RF therapy and machine to try to battle his leukemia. He didn’t win, but looks like the tech holds real promise and is […]
