The delightful math artist Vi Hart gives us a simple tip about efficiently using toothpaste. But that only takes a minute; about 45 seconds, actually. She still had a lot of time left for a standard internet video -and a lot of toothpaste, we can assume. So the video veers into art, then even into existential weirdness that no one was expecting. Some of the thinking behind it is explained at her site. Bonus: unlike most of her videos, we get to see Hart in this one. But we don't get to see her cleaning it all up. -via Metafilter
