The Barefoot Grandmother

These translucent plastic booties might remind you of what your grandmother wore in the 1950s if you’re a copywriter of a certain age. If not, then they’re plastic shoe covers with a white rubber sole. Package calls them “drizzle boots,” which is as cute as a grandmother, but it also says size Large, which is generous. Sole measures 11” heel to toe, so you decide, but definitely for your smaller large sizes. Closes over your ankle with a hook-and-loop strap.

RUBBER STOPPER

Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in a friendly orange and fit (13 mm) dia openings. The orange are 9/16" across the top, which has a dimple in the center, and 9/16" top to bottom. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

Burns 90ml of denatured alcohol and comes with a heat shield (packed inside the reservoir) and a burner cap. Don't forget to remove the little rubber plug - it's there to cover the holes in the copper tube when not in use. And this is lab equipment, so resist the temptation to use it under a chafing dish; initially, it flares up a tad more than is good for Swedish meatballs.
