Description
English: Made by myself. I melted a borosilicate capillary tube with a blowtorch into the shape (a en:cantilever beam) seen, clamped it in a micrometer (that's what micrometers are for, yes?), and photographed it vibrating. Flash photo + 1/8 second exposure to show vibration and a frozen moment in one picture.

A micrometer was used because it has carbide faces which are four times stiffer than glass (and twice stiffer than steel), makes for an excellent cantilever beam mount. Though I've had problems with poorly clamped beams, this probably makes no difference but it makes me sound smarter.
