Its crazy how individualistic life is, yet all we crave is people’s affection.
Soap bubbles are ephemeral creations. The slightest prick will send them tearing apart in the blink of an eye. It may come as a surprise, therefore, that dropping a water droplet through a bubble will not break it. Instead, the bubble will heal itself using the Marangoni effect. In a soap bubble, the soap molecules act as a surfactant, lowering the surface tension of the water and allowing the fragile structure to hold together. When the water drop impacts the bubble, the local surface tension increases because of the relative lack of soap molecules. This increase in surface tension pulls at the rest of the bubble, drawing more soap molecules toward the point of contact. The effect evens out surface tension across the surface and stabilizes the bubble. You can test the effect at home, too. If you wet your finger, you can poke a soap bubble without popping it.

If you roll a circle around a circular perimeter with twice the radius of the circle (think Spirograph, guys) each point on the circumference of the smaller circle actually moves along a straight line. The above video is the proof. (It’s too long to gif, just watch it!)
circumhorizontal arcs photographed by (click pic) david england, andy cripe, del zane, todd sackmann and brandon rios. this atmospheric phenomenon, otherwise known as a fire rainbow, is created when light from a sun that is at least 58 degrees above the horizon passes through the hexagonal ice crystals that form cirrus clouds which, because of quick cloud formation, have become horizontally aligned. (see also: previous cloud posts)
Food colouring in corn syrup. Watch as they rotate it 5 times one way and then 5 times back.
Your mind is now blown.
This is an example of the strange things that happen in fluids with low Reynold’s number. Reynold’s number is a ratio of the inertial forces and the viscous forces in the fluid. When the viscosity is high and the inertial forces are low fluids behave very differently to the way we are used to. Remember that next time you are trying to swim in honey.
I giffed the original video for your viewing ease. Enjoy.
