Stall:
🌀Hurricanes are steered by global winds
🌀The winds that surround a hurricane (environmental wind field) guide the hurricane
🌀When the environmental wind field becomes weak, the #hurricane may stall, especially if it’s not being influenced by high/low pressure systems
Stadium Effect:
🌀The eyewall encloses the eye of a #hurricane with surrounding thunderstorms
🌀If you are in the eye, you can see the #eyewall stadium effect (clouds stack up like a stadium)
🌀The #eye is the calmest part of the storm, you can even see blue sky during the day

Sliding Shenanigans:
🌊Play or locomotion
🌊A study found that a group slid 16 times in under 60 seconds
🌊Some slid down the same route more than once, indicating that sliding [while an economical form of locomotion] is #play behavior

We Will Stick Together:
💦Trimethylsilanol-treated sand and water
💦Treat normal sand with trimethylsilanol ((CH3)3SiOH) vapor to make it #hydrophobic (repels water)
💦Replaces the #hydrophilic hydroxyl (-OH) groups on the sand molecules’ surface with #hydrophobic siloxaneones
Eruptions, Earthquakes, Emissions:
🌎Red = Volcanic eruptions since 1960
🌏Blue = Earthquakes since 1960
🌍Yellow = Volcanic gas emissions (sulfur dioxide, SO2) since 1978, the first year satellites were available to provide global monitoring of #SO2

Shark Steals Bait Bag:
🦈Sharks have a trick called “gastric eversion” up their proverbial sleeve
🦈If a shark wants to eject its belly contents, it just flips its stomach out of its mouth (like turning your pockets inside out to empty them)
🦈Cleans out meal debris it gathers
New York’s Heartbeat:
🗽The flow of people in Manhattan, hour by hour, over the course of a week (13 miles long, 2 miles wide)
🗽Manhattan’s population swells considerably, like clock-work, every Monday through Friday
🗽Manhattan’s dynamic population

Starry Night:
🌌”The sight of stars always makes me dream,” Vincent Van Gogh wrote in a letter to his brother Theo
🌌Even at the time he had been admitted to an institution in the South of France, he enjoyed painting the starry night skies that he saw there
