Let’s Begin…

The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about strontium. Discover strontium with a trip to the village of Strontian, a flame test and some footage of nuclear explosions!

Extremely bright, modern, luminous paints that contain strontium can glow in the dark. Their glow comes from efficiently absorbing light from their surroundings, and then slowly releasing it over the course of minutes or even hours. Even the professor didn't know that!
