Nifty thrifty hint and Doctor Who musings.

You know these days when you travel by air, you have to have tiny bottles of anything even remotely liquid including toothpaste. Small travel sized tubes of toothpaste are very expensive for what you get and not refillable. Until now. Here's a Youtube demonstration on how to refill one of those small tubes from a large one using a small piece of vinyl tubing. *Very* useful to know. It does use non-metric measurement so for the 5/8" tube with a 1/2" in inside diameter he talks about, it measures out about 15mm or 1.5 cm. with an inside measurement of 12 or 13 mm from what i can tell but a hardware store should be able to convert it more accurately anyway if there's a need.
