…Sleep is strange?

Sleep Stages

Sleep is one of those strange things that everyone does but no one really understands. Thankfully, HowStuffWorks has come to the rescue with an article titled “How Sleep Works”. If you’ve ever wondered why people sleep, how people sleep, or what causes dreams, this is the article for you. If you’ve never wondered, then good night, and good luck.

…Fish can get tattoos too?

I recently picked up a few new fish for my tank, but somehow I missed the latest innovation in the fish market: the fish tattoo. Done with either dyes or a low level laser, the tattoos can be customized to be or say anything you wish. The days of designer fish are upon us.

…Grapes make plasma in your microwave?

And you thought all science projects were boring. This video walks you through the process of creating a glowing plasma ball in your very own microwave using only a standard green grape, a glass, and science. How does it work?

    “Grapes are full of electrolyte, an ion-rich liquid “grape juice” that conducts electricity. Each grape-half serves as a reservoir of electrolyte, connected together by a thin, weakly conducting path….the skin in this case. Microwaves cause the stray ions in the grape to travel back and forth very quickly between the two halves. As they do this, the current puts excess energy into the skin bridge, which heats up to a high temperature and eventually bursts into flame. At this point, the traveling electrons arc through the flame and across the gap, ionizing the air to a plasma (which itself can conduct electricity) and creating the bright flashes you see”.

It’s science.

…BumpTop makes your computer act like your desk?

Here’s a unique interface called the BumpTop. Check it out before Apple buys it and uses it for their next iPoderation, ala CoverFlow and the two fingers zoom thing.

Bonus: Here’s why BumpTop isn’t exactly like the way you normally interact with your documents:

Double Bonus: Here’s why you don’t let the designers rap your infomercials:

…Rockets are powerful?

XCOR Rocket Engine

This is what the test firing of a 7,500 pound thrust rocket engine powered by liquid methane and liquid oxygen looks like. It’s built by XCOR Aerospace, and is probably what’s going to power NASA’s future space missions. I just want to know if they have a way to mount it in the back of a Honda yet.

…The wood frog is amazing?

The wood frog (Lithobates sylvaticus) can do something quite astounding:

“You mean hours after it thaws it’s going to do it with a lady?”

…Money makes power?

Penny-Powered LED

With 13 dimes, 13 pennies, 13 paperclips, salt water and an ice cube tray, you can make a 1.5-volt battery, powerful enough to light up an LED. Is there any better way to spend $1.43?

…You can forecast your forecast?

Forecast Advisor

Forecast Advisor is unique because it not only tells you the weather, it forecasts which of your local weather services are going to be accurate. Sadly, I’ve only got about an 80% chance of dressing appropriately if I listen to any of my local weather forecasts.

…The brain doesn’t like to practice?

According to a Stanford University study, no matter how often you practice something, you’ll never be able to do it the same way every time because your brain can’t plan the action in the same way every time. “It’s as if every time the brain plans a movement, it has to start form scratch. Practice and training can help improve certain actions, but humans and other primates simply aren’t wired for consistency like machines or computers”. So it’s not true; practice doesn’t make perfect. Who knew?
