We love this made-for-kids series of videos, Circuit Playgroundby MIT engineer and Adafruit Founder Limor Fried (in the pink hair) and her robot friend ADABOT. For this excellent DIY project — and to find out what’s going on inside of the batteries that you use — get some lemons, pennies, galvanized nails, some aligator clips, and an LED, then watch their second video in the series, B is for Battery.

And if you missed it, watch A is for Ampere.

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.
