Question Your World - Question Your Coffee



Did you have any coffee today? A lot of people did. The United States moves about 400 million cups of coffee every day! Everything from intricate gourmet coffee to the basic cup of plain coffee. Even the basic cup of coffee is still very complex, holding over 1500 chemicals! The most familiar is caffeine, of course. It takes caffeine about 30 minutes to be fully absorbed by our bodies. Once in the bloodstream, it actually does enhance thought process and the body's capacity for physical activity.

Also, coffee contains antioxidants. Actually, Americans get more antioxidants from coffee than any other food or beverage!

Several studies have suggested that coffee may even reduce the risk of various diseases such as type 2 diabetes, Parkinson's, and Alzheimer's!

Question of the Week

Fruitcake facts:
  • The average fruitcake weighs 2 pounds.
  • Fruitcake has the same density as mahogany.
  • Fruitcake has been around since Roman times.
  • In the 18th century, fruitcake was outlawed in Europe.
  • Almost 3000 pounds of fruitcake were delivered to Iraq in 2006.
Can you answer this question:

What percent of people who received a fruitcake as a gift would throw it away?  What percent would regift it?

Did you receive a fruitcake as a gift this holiday season?  You can regift it to the Science Museum of Virginia!  Join us for Fruitcake Science on Wednesday, December 29 and watch all the fun we have with fruitcake.

Answer:  47% of people who receive the gift of fruitcake would throw it away immediately.  Another 11% would regift it.  So more than half (58%) would not keep it or eat it.  You have to wonder how many fruitcakes are continually regifted for years and years... maybe since Roman times???

More “Turkey Day” Trivia: Thanksgiving dinner

Turkey meat:  white vs. dark - What causes the color difference between white and dark turkey meat? The type of muscle fiber determines the color of the meat. Dark turkey meat has slow contraction muscle fibers. Slow contraction muscle fibers, sometimes called slow twitch muscle fibers, are used for extended muscle contraction in endurance activities and are supplied with lots of blood vessels, mitochondria, and myoglobin pigments, which give the red color to the meat. White turkey meat, on the other hand, has fast twitch muscle fibers for short bursts of strength and speed. Fast twitch fibers have a poorer blood supply, and fewer mitochondria and myoglobin, and tire quickly.

Cranberries – Of all fresh fruits, cranberries contain the most phenols, a type of disease-fighting antioxidant. Phenols and polyphenols are strong antioxidants and many scientists believe antioxidants protect the heart.

Yams vs. sweet potatoes - A yam is not the same thing as a sweet potato. Although yams and sweet potatoes are both angiosperms (flowering plants), they are not related botanically. Yams, native to Africa and Asia, are a monocot (a plant having one embryonic seed leaf) and are related to lilies and grasses. Sweet Potatoes are a dicot (a plant having two embryonic seed leaves) and are in the morning glory family. Yams are starchier and dryer than sweet potatoes.

Pumpkin pie - Most pumpkin fillings are really custard-type fillings with eggs acting as "gelling agents". They're able to do this because proteins in the eggs unwind as they are beaten and hold the pumpkin and liquids in a gentle mesh. As it cooks, it coagulates or sets and forms a custard-like filling. If the filling is cooked too long, the protein network contracts and shrinks, causing the filling to crack across the top. To prevent the cracking, cook it a little less this year. Remove it from the oven while the center still jiggles slightly if you give it a gentle shake. It may look like it still needs a little more cooking, but remember because of latent heat, it will continue to cook after it is removed from the oven.

"Turkey Day" Trivia

Want to wow your guests at the Thanksgiving dinner table with your incredible knowledge of turkey trivia?  Check out these "Turkey Day" facts! 

  • Most farm raised turkeys are White Hollands. They cannot fly.
  • An adult turkey has about 3500 feathers. Big Bird’s costume (from Sesame Street) was made from nearly 4000 white turkey feathers, dyed yellow.
  • Wild turkeys can glide almost a mile without flapping their wings. Over short distances, they can fly 55 mph and run 20 mph.
  • Acorns are the wild turkeys’ favorite food. Because they have a poor sense of taste and smell, they choose acorns by size and shape.
  • A turkey’s head will change colors when it’s excited.
  • Wild turkeys spend the night in trees.
  • A male turkey is called a tom, the female is called a hen and the babies, poults. Immature turkeys are called jake (male) and jenny (female).
  • How to tell toms from hens:
    • Toms are larger, have longer legs and bigger heads. Their wattle (growth under the chin) and snood (fleshy growth over the bill) are also longer.
    • Toms grow a beard – long black feathers on their chest. The beard grows about 4 inches per year and keeps growing throughout their lifetime. Eventually, it drags the ground.
    • Male turkeys gobble and females make a clucking sound.
  • During mating season, a male turkey gobbles loudly and struts around, puffing out his chest, fanning his large tail and dragging his wingtips on the ground.
