Taylor Speed Stir

And you know what else you can use it as? ... a timer.

Some tests require you to wait a minute or two after adding reagents, just turn the thing on (with its backlight on) - it'll shutdown after exactly 1 minute. Repeat as necessary.

Very handy if your timer from the dollar-store refuses to work right now when you need it (which of course never ever happens ...)
