Microwaving Water!
A 26-year old man decided to have a cup of coffee. He took a cup of water and put it in the microwave to heat it up (something that he had done numerous times before). I am not sure how long he set the timer for, but he wanted to bring the water to a boil. When the timer shut the oven off, he removed the cup from the oven. As he looked into the cup, he noted that the water was not boiling, but suddenly the water in the cup ‘blew up’ into his face. The cup remained intact until he threw it out of his hand, but all the water had flown out into his face due to the build-up of energy. His whole face is blistered and he has 1st and 2nd degree burns to his face which may leave scarring.

He also may have lost partial sight in his left eye. While at the hospital, the doctor who was attending to him stated that this is a fairly common occurrence and water (alone) should never be heated in a microwave oven. If water is heated in this manner, something should be placed in the cup to diffuse the energy such as a wooden stir stick, tea bag, etc, (nothing metal).

General Electric’s Response:

Thanks for contacting us; I will be happy to assist you. The e-mail that you received is correct. Microwaved water and other liquids do not always bubble when they reach boiling point. They can actually get superheated and not bubble at all. The superheated liquid will bubble up out of the cup when it is moved or when something like a spoon or tea bag is put into it.

To prevent this from happening and causing injury, do not heat any liquid for more than two minutes per cup. After heating, let the cup stand in the microwave for thirty seconds before moving it or adding anything into it.

Here is what a local high school science teacher had to say on the matter: ‘Thanks for the microwave warning. I have seen this happen before. It is caused by a phenomenon known as super heating. It can occur any time water is heated and will particularly occur if the vessel that the water is heated in is new, or when heating a small amount of water (less than half a cup).

What happens is that the water heats faster than the vapor bubbles can form. If the cup is very new, then it is unlikely to have small surface scratches inside it that provide a place for the bubbles to form. As the bubbles cannot form and release some of the heat that has built up, the liquid does not boil, and the liquid continues to heat up well past its boiling point.

What then usually happens is that the liquid is bumped or jarred, which is just enough of a shock to cause the bubbles to rapidly form and expel the hot liquid. The rapid formation of bubbles is also why a carbonated beverage spews when opened after having been shaken.’

If you pass this on
, you could very well save someone from a lot of pain and suffering.


These are a set of questions and answers that actually appeared on an Australian tourism website. It’s nice to see a government agency that doesn’t take itself too seriously.

Note that the nationality of the person asking the question is indicated in parentheses.

Q: Does it ever get windy in Australia? I have never seen it rain on TV, how do the plants grow? (UK) 
A: We import all plants fully grown and then just sit around watching them die. 

Q: Will I be able to see kangaroos in the street? (USA) 
A: Depends how much you’ve been drinking.

Q: I want to walk from Perth to Sydney – can I follow the railroad tracks? (Sweden)
A: Sure, it’s only three thousand miles. Take lots of water. 

Q: Are there any ATMs (cash machines) in Australia? Can you send me a list of them in Brisbane, Cairns, Townsville and Hervey Bay? (UK) 
A: What did your last slave die of?

Q: Can you give me some information about hippo racing in Australia? (USA) 
A: A-fri-ca is the big, triangle-shaped continent south of Europe.
Aus-tra-lia is that big island in the middle of the Pacific, which does not…
Oh, forget it. Sure, the hippo racing is every Tuesday night in King’s Cross. Come naked.

Q: Which direction is north in Australia? (USA) 
A: Face south, and then turn 180 degrees. Contact us when you get here, and we’ll send the rest of the directions.

Q: Can I bring cutlery into Australia? (UK) 
A: Why? Just use your fingers like we do.

Q: Can you send me the Vienna Boys’ Choir schedule? (USA)
A: Aus-tri-a is that quaint little country bordering Ger-man-y, which is…  
Oh, forget it. Sure, the Vienna Boys’ Choir plays every Tuesday night in King’s Cross, straight after the hippo races. Come naked.

Q: Can I wear high heels in Australia? (UK) 
A: You are a British politician, right?

Q: Are there supermarkets in Sydney, and is milk available all year round? (Germany) 
A: No, we are a peaceful civilization of vegan hunter/gatherers. Milk is illegal.

Q: Please send a list of all doctors in Australia who can dispense rattlesnake serum. (USA) 
A: Rattlesnakes live in A-meri-ca, which is where YOU come from. All Australian snakes are perfectly harmless, can be safely handled, and make good pets.

Q: I have a question about a famous animal in Australia, but I forget its name. It’s a kind of bear and lives in trees. (USA) 
A: It’s called a Drop Bear. They are so called because they drop out of gum trees and eat the brains of anyone walking underneath them. You can scare them off by spraying yourself with human urine before you go out walking.

Q: I have developed a new product that is the fountain of youth. Can you tell me where I can sell it in Australia? (USA) 
A: Anywhere significant numbers of Americans gather.

Q: Do you celebrate Christmas in Australia? (France) 
A: Only at Christmas.

Q: Will I be able to speak English most places I go? (USA)

Ancient Whale Bones Discovered in Desert, Parents Outraged by Hooters Waitress’s Visit to Special-Needs School

Paleontologists in Chile have made a surprising discovery in the desert. Scientists uncovered what appears to be a massive graveyard of whale bones in

Copiapo, more than a half-mile from the ocean. More than 80 whales, including 25 complete skeletons, were found in one of the driest deserts in the world. There is currently a construction project to widen the highway near the Atacama Desert, where the bones were found. Scientists believe the bones could be between 2 million and 7 million years old. So how did the whales make their way from the ocean to the desert and end up so close to one another when they died? Scientists have many theories: Maybe the area was once a lagoon and it dried up, maybe there was a giant wave that flung the whales onto shore, or maybe a giant earthquake sealed them off. Whale bones were not the only find for the paleontologists. A dolphin carcass with walrus-like tusks was also uncovered. Scientists say this discovery gives them a glimpse of ancient sea life. One paleontologist said, “The fossils are exceptionally well preserved and quite complete–a rare combination in paleontology and one that will likely shed light on many facets of the . . . ecology and evolution of these extinct species.” People on social media are debating creationism vs. evolution theories. Some people are just waiting for a scientific explanation. Still others are saying they should “accept the biblical account of the flood.”

Parents in Clearwater, Florida, are upset after a certain speaker was brought in to talk to their kids at school. Brittany Morgan, a Hooters waitress, spoke during “the Great American Teach-In,” a career event at the special-needs school. Morgan discussed looking presentable at work, tipping, and Hooters charity work with the students at Calvin A. Hunsinger School. She did not wear the Hooters uniform (skimpy orange shorts, low-cut white tank top, flesh-toned hosiery, white socks, and white sneakers) to speak in front of the kids. One parent was still disturbed, saying, “It’s just the wrong message . . . like we’re telling them that you’re the bad kids and this is all you’ll be in life.” Some people on Twitter agree, saying, “Can we raise the bar for kids’ aspirations?” Morgan said she understands why the parents might be upset, but that there was nothing inappropriate about her speech. Morgan added, “Most of us are going to school. We’re aspiring to do other things in life. This isn’t our career.” The principal of Hunsinger, Stephani Bessette, defended Morgan’s appearance, saying “Working as a waiter or waitress to achieve higher goals should be commended.” Hooters states that its mission is “to provide a family of hospitality and services that achieves excellence and enhances lifestyles of all who come in contact with the Hooters brand.”
