Workshop envy!

Workshop envy!

I don’t have my own workshop, just a desk in my bedroom that is more likely to have a pile of kid socks on it than an actual project. (Or, even more likely, it would have both projects and socks on it, making for a huge mess…) Consequently, I’m envious of and fascinated by other […]

Mercury “beating heart” demo video

This classic chemistry demo involves the use of toxic metallic mercury, so it’s one of those that is best to just watch on YouTube instead of trying yourself. The pulsing action is caused by surface tension effects–metallic mercury is oxidized at the surface of the drop to form a film of mercury (I) sulfate, which lowers the drop’s surface tension and causes it to flatten under its own weight. The flattening brings the drop into contact with the tip of a carefully-positioned iron nail, which reduces the mercury (I) sulfate back to metallic mercury, which in turn increases the drop’s surface tension and causes it to contract away from the nail. Thanks to YouTuber sciencevidds for sharing it with us. [via Boing and then some more Boing]

Built on a trailer base, this can be towed to public events to serve as a recruiting tool – offering a taste of soaring to many more people. And since it folds up tidily, it doesn’t require dedicated […]

Tree Branch Magnetic Hooks

The lichen growing from the bark is such a great texture to juxtapose against the galvanized metal. And their delicate woodland aesthetic belies the strength of the rare earth magnet embedded in the back.
