a show about the mysteries of sticky things, including a tape so strong it holds skyscrapers together, mummy glue and one item that has been life-altering for climbers: rock-shoe rubber.
part one. from www.japanprobe.com: sticky man wall crawler toys have been around for years, but nobody had ever bothered to build one the size of a human being. they've all been cheap and tiny little pieces of junk, never having climbed down anything much taller than the average household wall. all of that changed recently when the japanese tv show hey! spring of trivia decided to conduct a grand experiment.

remember the guys who did the coke and mentos geysers? watch what the team from eepybird get up to with sticky notes!
the creative folks at haneru no tobira bring us another wacky challenge: the participating comedians are expected to scale a wall covered with “magic tape” (velcro), jump from the wall to a rope, swing onto a platform covered with similar tape, and then leap onto another platform. those that fail fall into a bit of flour!
very good song but hard to get a hold of.

washington (reuters) - researchers have found a new "see-through" use for clear sticky tape -- it produces x-rays when it is peeled off the roll. the report in the journal nature confirms a theory dating back to 1930 -- that the process of peeling the tape releases energy not only in the form of a flash of visible light, but also an x-ray. many children hiding in closets have demonstrated that unwinding sticky tape produces sparks of light. the phenomenon is called triboluminescence and is caused by the movement of one surface against another. carlos camara of university of california, los angeles and colleagues used a motorized peeling machine to unwind a roll of tape in a vacuum. they generated enough x-rays to show the bones inside their fingers. "the tape has to be in the vacuum. your hand can be outside," camara said in a telephone interview on thursday. "if you unroll the tape on your office desk in ambient conditions you only get visible light. you don't get x-rays," he added. this is because gases in the air slow down the electrons that produce the x-rays. "what always makes x-rays in general is electrons that are moving very fast and suddenly get stopped," camara, a physicist, said. "they are flying from one side of the tape to the other as you separate them. you get something like a miniature lightning strike." this property might be used to make nuclear fusion, camara and his team said. all it would take is about 10 times as much energy as was produced during the experiment, he said. it might be possible to unroll the tape even faster to get the effect, camara said. "it's just an energy issue. we have managed to get x-rays with this. if you could go another factor of 10 you could get that much more energy and fusion would be proof of that much energy," he said. this would not be the kind of nuclear fusion that produces energy, or an explosion. unrolling the tape will require putting in more energy than would be produced, camara said. "obtaining nuclear fusion in the lab is not that hard. what is really hard is obtaining excess energy from nuclear fusion," he said. so-called tabletop nuclear fusion was achieved in 2005 -- but using conventional electricity that required more energy going in that was produced by the reaction. source
mexico city — the country that gave the world chewing gum is getting gummed up: the average square yard (meter) of mexico city sidewalk has 70 blobs of discarded chew. now mexico is responding with innovations ranging from expensive sidewalk steam-cleaners to natural chewing gum that breaks down quickly. it's even telling its citizens (gulp!) to swallow their gum. the general in the war on discarded chewing gum is ricardo jaral, mexico city's director for conservation of public spaces. he bemoans the blackened gobs that mar the newly restored 700-year-old downtown area and litter the lovely but porous hand-chiseled sidewalks along the city's main boulevard. he has purchased a fleet of german machines that clean sidewalks with steam and chemicals, and is looking at launching a public-awareness campaign. "when you finish chewing a piece of gum, you either have to put in a piece of paper and deposit it in a trash receptacle, or swallow it," jaral said. not so fast, says dr. nick desai, a pediatrician at the children's hospital at vanderbilt in nashville, tennessee. he said swallowing gum isn't a good idea. it usually passes through the digestive system, but can ball up with other objects and cause an intestinal blockage. "it's nothing to get too upset about if it happens," desai said. "but we shouldn't make a habit of it." jaral shrugged off such concerns today: "i've always swallowed my gum, and it's never done me any harm." the sticky problem involves the long-lasting, synthetic chewing gum base used since the 1940s to replace the latex-like chicle resin that ancient mayans had long collected from the sapodilla tree. the mayans chewed unflavored chicle to clean their teeth. modern chewing gum was born in the 1860s when mexican gen. antonio lopez de santa anna brought some mexican chicle to u.s. inventor thomas adams, who first experimented with it as a possible rubber substitute but later added flavorings and sold it as a treat. mexico largely forgot its natural, biodegradable gum base and wholeheartedly adopted u.s. synthetic gum. mexicans now chew an average of 2.6 pounds (1.2 kilograms) of gum each year, half what the average american chews but still among the highest rates in latin america. of course, gobs of discarded gum are a problem around the world. singapore once famously banned chewing gum outright to save its sidewalks, and still requires chewers to register at the pharmacy. the rid-a-gum company of staten island, new york, sells about 200 of its $3,500 cleaning machines a year. "it's a major, major problem for malls, schools, any kind of public facility," said rid-a-gum owner jack hurley. mexico says the solution may lie in the past, with its natural chicle producers. in the jungles of southern mexico, manuel aldrete's cooperative of chicle harvesters is about to launch a line of organic chewing gums. he says his product breaks down far more quickly on park benches, streets and sidewalks. "it dries up, breaks down and turns to dust," aldrete said. "when it's hot it is sticky, but when it cools it dries up and peels off almost automatically." he estimated that in colder climates it would take up to six months to break down, and much less time in hotter areas. but it's still a small piece of the market: only about 300 tons of chicle are produced annually, a tiny fraction of the tens of thousands of tons that would be needed to supply even mexico's domestic market. plus, aldrete notes, the "environmentally conscious consumers" who buy organic gum probably aren't the same people spitting their chews onto the sidewalk. "they're the kind who are probably going to find a garbage can and deposit it in the one labeled 'organic waste,'" he said. source
