In the same way that we use reusable metal water bottles and sippy cups for kids on-the-go, the team at Keep Cup is promoting reusable coffee containers for adults on-the-go in this promo video called Salute the Reuser.

Easy experiment: Drink orange juice. Brush your teeth. Drink orange juice again. What just happened?

From Bytesize Science, an explanation as to why most toothpastes change the taste of orange juice. The video includes an intro on the five basic tastes that we’re able to detect: sweetness, sourness, saltiness, bitterness, and umami — a Japanese word that we’ve borrowed to describe a “pleasant savory taste” or “a pleasant, brothy or meaty flavor” — and the ingredients of toothpaste.
