POPSRC Helicopter # Unique indoor fly bird : can fly flexibly even in the small space # Ultralight appearance: super lightweight, will not demage the items even play indoors # Innovative fly movements: this dragonfly helicopter can fly like real insect, the farthest remote control distance is about 50 feet. It can take off on the smooth surface, complete high-altitude circumferential flight, hover, diving, and landed in a glider-type. # Two operate mode: "Beginner" and "Expert" mode on the remote control, great for junior and senior players to enjoy the fun of flying. # Rear: the ribbon of the tail is an ideal training assistant tool, especially to help you control the speed and stability of the flight. # Solid material, flexible appearance: durable carbon fiber material, flexible body design, made this dragonfly helicopter can withstand any collision. # Eye indicator light: the eye light can be used to check the state of the helicopter. Turn on the power of the remote control:

POPSWeather Balloons To Control Climate Basic calculations suggest that, in maybe a week or less, ten million tons of raw materials could produce enough balloons to cover the entire earth at twenty miles altitude. That may sound like a lot of material, but in fact it's about the same amount that goes into building 100 miles of a modern highway—so it's well within reach of even a small nation to acquire the materials if they have the hardware and software and a desire to control the weather of the earth. Shifting mirrors inside balloons to make some areas warmer and others colder, to make some wetter and some drier gives at least rudimentary power for Josh's "Nano-enabled Climate Control for the Earth." These balloons may well be helpful in slowing, stopping, or even reversing the trend of global warming, as long as we recognize the very real danger of unforeseen, unintended, and possibly irreversible consequence.

POPSUrban Myths about Viruses... What?!? Doesn't anyone read scientific journals/reporting any more. Viruses wrap up in fats to ride out cold weather outside or at high altitude. They catch a ride on a water molecule (whether water or ice). They end up on your coat, head, hands, mouth, eyes, etc. Once the temperature increases, they 'thaw' out and become 'active'. Learn more by looking at my clip about how the flu can make you fat. Enjoy! Certainly, trading viruses with your friends, family, and colleagues is common. Additionally, you are more likely to catch what other people have if you breathing the same air. However, most viral infections start as an invasion from outside the body.

POPSStudying volcanoes with flying balloons :) "The balloons are piloted remotely by satellite link," Durant explained, "with flight visualization using Google Earth. We were looking at tropospheric volcanic emissions of sulfur dioxide, carbon dioxide and water, which can be hazardous to human and animal health and degrade ecosystems."

POPSUS Intel: Iranian nuclear strike on U.S. ?
“The only explanation we can find is that Iranians are figuring out how to launch a missile from a ship and get it up to altitude and then detonate it,” “And that’s exactly what you would do if you had a nuclear weapon on a Scud or a Shahab-3, and you wanted to explode it over the US.” "If a crude nuclear weapon were detonated anywhere between 40 kilometers to 400 kilometers above the earth, in a split-second it would generate an electro-magnetic pulse that would cripple military and civilian communications, power, transportation, water, food, and other infrastructure" Asked how many Americans would die if Iran were to launch the EMP attack it appears to be preparing, Graham gave a chilling reply. “You have to go back into the 1800s to look at the size of population” that could survive in a nation deprived of mechanized agriculture, transportation, power, water, and communication. “70 to 90 percent of the population would not be sustainable after this kind of attack”.
