易 on Instagram: "The Prince Rupert’s Drop is a teardrop-shaped glass marvel. Formed by cooling molten glass in water, its surface compresses while the core stays under tension, creating incredible strength. The bulbous head can withstand up to 40,000 pounds of force, but a small nick to its tail triggers an explosive shatter. This content is shared strictly for educational purposes.

The Space Doctor on Instagram: "The creator and the destroyer. The Andromeda and Milky Way galaxies are expected to collide in about 4.5 billion years. Surprisingly the sun becomes a red giant in around the same time. So what's a red giant? When a star is about to die it increases in size, our sun will do the same. This happens before the Andromeda collides with our milky way to form Milkromeda. Is it a kind of backstab done by sun? Or something else. #space"
