San Francisco's Exploratorium is gearing up for Earth's next total eclipse. And during the build up, they've released a set of videos explaining the types of things you can observe during an eclipse. One of those is how the Sun's gravity can bend light around it as predicted by Albert Einstein.
In this video they use a bright blue LED as a stand in for star light to explain how light can be bent by gravity. To simulate your own starlight, check out some of our blue LED strips!
