SNOT-COPTER: Drone at Work
Spider Magazine for Kids|February 2021
THE BOAT IS on the move. It speeds over icy waters toward a humpback whale.
Dionna L. Mann

Holly Fearnbach, John Durban, and Lance Barrett-Lennard are on board. They’re whale scientists on a mission. They’re about to use a hexacopter—a remote-controlled drone with six propellers—to collect some whale snot.

Whales are mammals. They have lungs and cannot breathe underwater. Whales hold their breath when underwater, then rise to the surface to breathe, using their blowholes kind of like how humans use their two nostrils. What you see spurting out from a whale’s blowhole isn’t a plume of water—it’s actually condensed whale breath! As the whale exhales, its breath comes out warm and mixed with droplets of snot. The warm air from the whale’s lungs condenses the cold air and forms a misty, snot-filled plume.

A humpback whale like the one Holly, John, and Lance have been tracking can exhale at a speed of 300 miles per hour, causing the blow to reach nearly 10 feet high or higher! As their boat approaches the giant whale, the three scientists get the hexacopter ready.

The hexacopter is battery powered. It’s small, sturdy, and lightweight. The scientists have attached a powerful digital camera to its bottom side, a collection plate to its front, and a petri dish to its top. When a humpback blows, the hexacopter is a perfect tool for collecting the whale’s snot.

PUBLISHING AMID A PANDEMIC: How Board Games Survived and Thrived in 2020

COVID’s lasting impacts on our health and economy are still far from being understood. It will take many of us years, perhaps even a decade, to unravel what has changed in the last year. But some patterns are emerging, at least in the board gaming hobby, that indicate many publishers were well ahead of the curve even before the threat of a pandemic affected their supply chains worldwide. As the world began locking itself down to quell the threat of COVID-19, people continued to find solace in hobbies. Soon, the business journals and magazines of the world began tracking the increase of sales across a wide swath of interests as people did anything and everything to take their minds away from the weight of a pandemic circling the globe. Turns out, everything from toys, guitars, crafts, and board games were selling well despite a deflated economy. Report Linker’s “Board Games Market - Global Outlook and Forecast 2021-2026” estimates that sales in the hobby will grow by 13 percent in the next five years, even with continued lockdowns. But what about the hobby as a whole? This article examines how 2020 affected the board gaming industry through three facets — big box stores, local board gaming cafes and stores, and the digital space — and how the pandemic has shaped them in the interim as well as moving forward. Is this projected forecast of its growth still as rosy?

SLIDING FOR ADVENTURE

For the last 25 years I’ve been riding off road on everything from a 450cc lightweight to a heavily laden 1200cc adventure motorcycle. Although I was usually able to handle anything through rough terrain at slower speeds, I struggled at higher speeds on loose surfaces. And the biggest pucker moments occurred while approaching tight turns on gravel roads at high speed—barely navigating them safely.
