When you sip soda through a straw, you are utilizing the simplest of all suction mechanisms. Sucking the soda up causes a pressure drop between the bottom of the straw and the top of the straw. With greater fluid pressure at the bottom than the top, the soda is pushed up to your mouth. ­
Fact #21: Dogs are capable of understanding up to 250 words and gestures, can count up to five and can perform simple mathematical calculations. The average dog is as intelligent as a two-year-old child.
1. Picture perfect Raspberry Pi

David Hunt, a Linux software engineer and photographer had been thinking about embedding a computer in a DSLR camera for years, but always found high costs to be a barrier. But then came the Raspberry Pi to smash that hurdle. With the $35 he re-purposed one of his old battery grips into a camera accessory that can transmit just-shot images in real-time to a computer via Wi-Fi, and also control the camera remotely from a computer. "There’s plenty of work to be done on the software side of things, but the prototype is working," he says.

2. Supercomputer Raspberry Pi

Only because the Raspberry Pi is sized small, it doesn't mean that it should not be taken seriously. Simon Cox, a computer engineer at the UK's University of Southampton together with a team of engineers had built a supercomputer by tying 64 Raspberry Pi systems together. Cox also enlisted the help of his 6-year-old, LEGO-obsessed son, who built the supercomputer's rack out of the plastic building blocks.

The University's computer cluster has a total of 64 processors and one terabyte of memory (care of 64 different 16GB SD cards, one for each Raspberry Pi), and uses ethernet switches to link the systems. 

3. The beets

Scott Garner's Raspberry Pi creation mixes vegetables, music, and wordplay. His BeetBox allows users to play drumbeats by touching real beets. Garner says that his BeetBox was easy to put together, thanks to the versatility of the Pi platform. "The biggest challenge was getting [the Pi] to communicate with the capacitive touch sensor," he says. The beets, however, proved less pliable than the Raspberry Pi. "Things got tricky when the vegetables dried out. Their capacitance changed, which threw the sensor off," Garner says. 

4. Palmtop Pi

“I just wanted to see if it was possible to make an ultraportable, mobile Raspberry Pi that you can take to go,” explains Nathan Morgan, founder of the laptop parts site Parts-People.com.

Morgan's Pi-to-Go minicomputer sports a 640-by-480 pixel display; a touchpad; a 64GB solid-state drive; and support for Wi-Fi, Bluetooth, and HDMI. "It's not the lightest or thinnest handheld," Morgan was quoted in an interview, "but I didn't care about that when I was building it. I just wanted it to meet all the criteria for being a portable Pi."

5. Beer can keyboard

While this Beer Keyboard isn't the most practical peripheral in the world, it's possibly the most inebriating. Powered by Raspberry Pi, this QWERTY keyboard for the over-21 crowd is tricked out with 44 beer cans from a Prague-based brewery. The company Robofun Create built the system, which requires you to tap the letters on the tops of beer cans to produce letters on a plasma screen above it.

6. Life of Raspberry Pi

A group called FishPi is ready to send the Raspberry Pi to sea. The group is planning an Atlantic crossing for a drone boat with its navigational systems controlled by the single-board computer.

Measuring 20 inches from stem to stern, the vessel is powered by a 130-watt solar panel. As the boat crosses the Atlantic, it will collect scientific measurements. "We wanted to do something that went outside of the normal bounds of conventional thinking," the group explained on its website. 

7. Teeny tiny arcade

Jeroen Domburg didn't know what to do with this machine when he bought his first Raspberry Pi. "It's always useful to expand your toolset with something powerful and cheap," he has said. What he eventually cooked up is perhaps the smallest arcade-style gaming cabinet in the world. The cabinet is made of laser-cut plastic and has a 2.4-inch TFT display. 

8. Pi Laptop

SK Pang Electronics took a slightly different tack in creating a portable computer with the Raspberry Pi board. It uses the monitor from the rear-view camera system of an automobile, a choice that required some power-supply tinkering, a mini-wireless keyboard, a USB power pack, and a cool laser-cut transparent base. 

9. Solar-powered FTP server

Raspberry Pi owners hungry for a serious challenge can consider building a solar-powered FTP server. The setup here includes a custom-built Raspberry Pi case with a solar panel on one side, and, on the other, compartments for the computer, with holes in all the right places for I/O ports and four AA rechargeable batteries. "You'll always have instant access to all your digital files, from anywhere with an Internet connection, and it won't cost a penny on your electricity bill," says David Hayward, who provides full details about the project here.

10. Sky Pi rig - Pi in the sky

Chasing high-altitude balloons has become sport for many who send GPS-enabled gear to the outer limits of the Earth's atmosphere, and then chase it as it floats down. And give an extra edge to his ballooning friends, Dave Akerman created his gear with a custom Raspberry Pi computer which sported a GPS radio, a webcam, and various sensors. He claims that, thanks to his Sky Pi rig, he was able to capture some of the highest images ever sent down from an amateur flight. He has blogged about his achievement and also posted a fascinating Flickr collection documenting his balloon's voyages. 
With the first Bitcoin ATM launching in Vancouver on Tuesday, some may question the validity of the digital currency and its efficacy in the modern world. Is this a venture doomed to fail, losing investors thousands if not millions of dollars in the process? Or is Bitcoin an emerging currency free from centralized oversight, high fees and the woes of the current economy?

Dreams can be fascinating, exciting, terrifying or just plain weird. Learn more about some of the things that researchers have discovered in these ten facts about dreams1. Everybody Dreams
1. Make brown-bag lunches for your roommate every morning. Give them to him/her before he/she goes to class.

2. Every time you enter the room, sit in a chair, lean back too far, and fall over backwards. Laugh hysterically for about ten minutes. Then, one day, repeat the falling-over exercise, but instead of laughing, get up, look at the chair sternly, and say, "It's not funny anymore." 

3. Read with a flashlight when the lights are on. Pretend to read without one when the lights are out, remarking every so often how great the book is. 

4. Get a surfboard, put it on your bed, stand on it, and pretend to surf for about fifteen minutes. Then, pretend to "wipe out" and fall off the bed onto the floor. Pretend you are drowning until your roommate comes over to "rescue" you. 

5. Keep a hamster as a pet. Buy a blender, and make milkshakes every day. Then, one day, get rid of the hamster. Make a shake using a lot of ketchup. When your roommate comes in, look at the shake, look at the empty cage, and tell your roommate, "I was curious." 

6. Make toast for breakfast every morning, but don't plug the toaster in. Eat the plain bread, looking at the toaster angrily, and complain that the toaster doesn't know what it's doing. If your roommate suggests plugging it in, go on a tangent about fire-safety hazards. 

7. Pack up all of your things and tell your roommate that you're going away to "find yourself." Leave, and come back in about ten minutes. If your roommate asks, explain that you're not a hard man to find. 

8. Never speak to your roommate directly. If you need to ask or tell him/her something, go to another room and call him/her on the phone. 

9. Every night, before you go to bed, beg your roommate for a glass of water. When he/she brings it, dump it on the floor and immediately go to sleep. If he/she ever refuses to bring you a glass of water, lie on the bed, and pretend to be dying of dehydration, making annoying gagging sounds, until he/she does so. 

10. Every time the phone rings, turn on the stereo at full volume and begin to violently slam-dance with your roommate. If he/she asks about it, say, "Oh, that damn hypnotist...." 

11. Hang a picture of your roommate on the wall. Throw darts at it. Smile at your roommate often, saying things like, "How nice to see you again." 

12. Get a can of beans. Label them, "Jumping beans." Eat them, and then jump around the room. Get another can of beans. Label them, "Dancing beans." Eat them, and then dance around the room. Get another can of beans. Label them, "Kill Your Roommate beans." Eat them, smiling at your roommate. 

13. Every time your roommate falls asleep, wait ten minutes, and then wake him/her up and say, "It's time to go to bed now. " 

14. Insist that your roommate recite the "Pledge Of Allegiance" with you every morning. 

15. Recite "Dr. Seuss" books, all the time. Eventually, think up melodies for the words and sing them, loudly, directly to your roommate. If he/she tells you to stop, act offended, and spend the day in bed. 

16. Put up traffic signs around the room. If your roommate doesn't obey them, give him/her tickets. Confiscate something your roommate owns until he/she pays the tickets.  - See more at: http://fooyoh.com/7633013#sthash.VKaJE7WB.dpuf
