Time for another fluids round-up! Here are your links:

  • Back in January 1919, a five-story-high metal tank full of molasses broke and released a wave of viscous non-Newtonian fluid through Boston’s North End. Scientific American examines the physics of the Great Molasses Flood, including how to swim in molasses. If you can imagine what it’s like to swim in molasses, you’ll know something of the struggle microbes experience to move through any fluid. They also discusses some of the strange ways tiny creatures swim.
  • In sandy desert environments, helicopter blades can light up the night with so-called helicopter halos. The effect is similar to what causes sparks from a grinding wheel. Learn more about this Kopp-Etchells effect.
  • Check out this ominous footage of a tornadic cell passing through Colorado last week.
  • If you want more of a science-y look to your drinkware, you should check out the Periodic TableWare collection over on Kickstarter.
  • Finally, wingsuits really take the idea of gliding flight to some crazy extremes. Check out this video of in-flight footage. Watch for the guy’s wingtip vortices at 3:16 (screencap above)! (submitted by Jason C)
