Cold Feet? (Or Hands?)


Cold Feet? (Or Hands?)

It won't be long until the frigid days of winter are upon us here in the Northeast. While opinions on cold weather differ from person to person (love it or hate it), we all agree there comes a point where it is just TOO COLD. Plus, it only takes about a 3 degree drop in body temperature to begin experiencing the effects of hypothermia. Keep reading to find out when being cold goes from being annoying to deadly.

As your body temperature drops to these levels, here's what you might experience:

  • 32-35°C (89.6-95°F) - Mild hypothermia: shivering, fast heart rate and breathing, some confusion
  • 28-32°C (82.4-89.6°F) - Moderate hypothermia: violent shivering, slow movements, stumbling, mild confusion, pale skin, lips/ears/fingers may appear blue
  • <28°C (<82.4°F) - Severe hypothermia: extreme difficultly thinking, speaking, or walking, puffy skin, vital signs are reduced or absent

Pretty.  Dangerous.


  • Closest planet to the sun
  • Roman God
  • Former car company
  • Chemical element
  • Toxic substance

Though the name has been used for many types of things, the element itself has been used throughout history in a multitude of applications, including paint, cosmetics, firearms, even dental fillings which are still used today. Keep reading to learn more about this unique but toxic liquid metal!

  • Mercury was used in Roman times as pigment in paint, a practice which continued all the way until 1991 (although as time went on it was used more as a fungicide rather than for color).
  • People once considered the liquid, silvery mercury to be so special that it had to have healing powers. They used it to treat everything from syphilis to parasites to simple cuts and scrapes.
  • Ever heard the phrase "mad as a hatter"? This comes from the mercury poisoning that many hat-makers suffered from using mercuric nitrate as a way to soften the felt used in hat making. 'Mad hatters' suffered slurred speech, tremors, and sometimes hallucinations.

Just Popping By!


Just Popping By!

Who doesn't love settling in to watch a movie with a big bowl of freshly popped, buttery popcorn? We know you've often pondered the science behind popcorn while you're waiting for the microwave to finish popping those kernels, or for the concession stand attendant to hand you a warm bag. Well wonder no more - we've got the scoop on how popcorn pops (sure to wow your friends and family during your next movie night!)

  • Popcorn kernels naturally contain oil and water plus starch, surrounded by an outer shell, or hull.
  • As they're heated, the oil and water gelatinize the starch inside the hull.
  • As the internal temperature reaches about 180°C, pressure inside the hull rises to about 135psi, and then POP!
  • The gelatinized starch spills out and immediately cools into the familiar popcorn shape we know and love.

Popcorn is 1 of 4 main types of corn, but it's the only one that POPS!

Pop Up 2" Freezer Boxes won't make the 'pop' sound when you assemble them, but they WILL save storage space and money (which we think is better)!

  • Ships flat/stores flat
  • Saves money by replacing less often
    • More durable than fiberboard
    • Impervious to moisture
    • Reusable - will not stick to icy racks or shelves
  • Fits into standard 2" freezer storage racks

Testing… Testing…


Testing... Testing...

With the world's largest sporting event currently taking place in Rio, and all the controversy about performance-enhancing drugs that inevitably follows, we dug up a few interesting facts about doping and some surprising banned substances in sports.

  • What, no coffee?! Caffeine was banned until 2004, due to it's ability to temporarily increase speed and stamina. However, since it was nearly impossible to distinguish casual use of caffeine from a doping attempt, the ban was lifted.
  • Horses also go through drug testing for equestrian events! Capsaicin, the active chemical in hot chilies, can be found in horse topical creams to alleviate pain and/or increase their leg sensitivity, particularly when jumping fences. Because of this, capsaicin is a banned substance for these 4-legged athletic partners.
  • Some athletes have resorted to blood doping by using blood transfusions to increase red blood cell count, thereby improving endurance.

Sports federations only started to test for
performance-enhancing drugs in the mid

No More Wires!

Bluetooth? What's a bluetooth? Yes, we know it's open wireless technology that shares data using short-wavelength radio transmissions, but what we didn't know was why it came to be called 'Bluetooth' (which frankly sounds a little bit more like the name of a band playing on campus)!

So, why is it called 'Bluetooth'? - The idea was inspired by 10th century King Harald Bluetooth. He united Danish tribes into one kingdom; Bluetooth technology unites communication into one universal standard.

And, why exactly was King Harald called 'Bluetooth'? - Rumor has it, he may have had a bad tooth that appeared 'blue' - Ouch! (blue actually meant dark back then!)

Bonus Fact! The Bluetooth logo contains the Nordic runes (aka letters) for the initials "HB"! Now that's serendipitous!
