Surface tension draws bubbles into spheres, but the balance of forces holding the sphere together is delicate. When pierced by a projectile, sometimes soap films can heal themselves, but often the film ruptures. Once a hole forms in the bubble, the film’s integrity is lost. Instead of holding the bubble together, surface tension pulls the soap film apart in a spray of thread-like ligaments that break into droplets. In the blink of an eye, the bubble is gone.

“In the first place, then, as is evident to all, fire and earth and water and air are bodies. And every sort of body possesses solidity, and every solid must necessarily be contained in planes; and every plane rectilinear figure is composed of triangles…”

Tetrahedron –> Fire
Cube –> Earth
Octahedron –> Air

A tiger mother lost her cubs from premature labour. Shortly after she became depressed and her health declined, and she was diagnosed with depression. So they wrapped up piglets in tiger cloth, and gave them to the tiger. The tiger now loves these pigs and treats them like her babies.

The kitchen is a fantastic place to witness the everyday beauty of fluid dynamics. Daria Khoroshavina and Olga Kolesnikova capture these delectable cooking-related GIFs on their Buttery Planet Tumblr. From pouring cream to drizzling syrup, there are countless examples of fluids in daily life. Check out their site for more awesome images and be sure to keep your eyes open for great examples of fluid behavior in your day-to-day life. (Image credits: Buttery Planet; via Colossal)
