Ok, sorry if this post is confusing. It seems to me that *technically* Thomas Hancock probably invented the rubber band in 1843. Working with Hancock, Stephen Perry patented it two years later in 1845, and generally gets credited with being the inventor.\n\nAnother name that gets floated around is Dr. Jaroslav Kurash, but that rumor seems to have originated with an errant Wikipedia entry. It has also been said that William H. Spencer invented the rubber band in 1923 when he was cutting them out of discarded rubber products. It seems to me that if Perry patented the rubber band in 1845, as multiple sources say he did, it was not invented 78 years later by Spencer.\n\nAnyway, I've pasted the two main versions below, along with a bunch of sources for you to check out. You can decide for yourself.\n\n----------------------------------------------------------------------\n\n\nIn 1845, Stephen Perry, of the rubber manufacturing company Messers Perry and Co., patented the rubber band to hold papers or envelopes together.\n\nThe first rubber band was developed in 1843, when an Englishman named Thomas Hancock sliced up a rubber bottle made by some New World Indians. Although these first rubber bands were adapted as garters and waistbands, their usefulness was limited because they were unvulcanized. Hancock himself never vulcanized his invention, but he did advance the rubber industry by developing the masticator machine, a forerunner of the modern rubber milling machine used to manufacture rubber bands as well as other rubber products. In 1845, Hancock's countryman Thomas Perry patented the rubber band and opened the first rubber-band factory. With the combined contributions of Goodyear, Hancock, and Perry, manufacturing effective rubber bands became possible.\n\nhttp://www.answers.com/topic/rubber-band\n\n--------------------------------------------------\n\nHere's the William H. Spencer version:\n\nOn March 7, 1923, William H. Spencer of Alliance, Ohio, obtained rejected inner tubes from the Goodyear Co. and began cutting them into bands in his basement. Spencer, who worked for the Pennsylvania Railroad, began trying to sell his rubber bands to office-supply stores and paper and twine outlets. \n\nOne day he noticed the Akron Beacon Journal blowing across lawns and persuaded that paper to bind them with his bands. He talked the Tulsa World into doing the same, and persuaded grocers to use his rubber band instead of string to secure produce. \n\nSpencer continued working for the railroad for 14 years while building his rubber-band business at his Alliance plant. By 1944 he was able to open a second plant in Hot Springs, Ark. In 1957 he opened another, in Franklin, Ky., and one in Salinas, Calif. in 1988. The Alliance Rubber Co. now produces more than 2 million pounds of rubber bands a month in addition to other office, mailing and packaging products and sells to more than 30 countries. \n\nhttp://www.enquirer.com/editions/2003/03/07/loc_ohiodate0307.html

The oldest pair of skates known date back to about 3000 B.C., found at the bottom of a lake in Switzerland. The skates were made from the leg bones of large animals, holes were bored at each end of the bone and leather straps were used to tie the skates on. An old Dutch word for skate is "schenkel" which means "leg bone". \n\nAround the 14th Century, the Dutch started using wooden platform skates with flat iron bottom runners. The skates were attached to the skater's  shoes with leather straps.  Poles were used to propel the skater. Around 1500, the Dutch added a narrow metal double edged blade, making the poles a thing of the past, as the skater could now push and glide with his feet (called the "Dutch Roll"). \n\nIn 1848, E. V. Bushnell of Philadelphia, PA invented the first all steel clamp for skates. \n\nIn 1865, Jackson Haines, a famous American skater, developed the two plate all metal blade. The blade was attached directly to Haines' boots. The skater became famous for his new dance moves, jumps and spins. Haines added the first toe pick to skates in the 1870's, making toe pick jumps possible. \n\nThe first artificial ice rink (mechanically-refrigerated) was built in 1876, at Chelsea, London, England and was named the Glaciarium. It was built near the King's Road in London by John Gamgee. \n\nIn 1914, John E. Strauss, a blade maker from St. Paul, Minnesota, invented the first closed toe blade made from one piece of steel, making skates lighter and stronger. \n\nThe largest outdoor ice rink is the Fujikyu Highland Promenade Rink in Japan, built in 1967 and boasts an ice area of 165,750 square feet-- equal to 3.8 acres.

you don't need an instuctor, it's hard at first, but it's very easy to learn.  Just have a friend of yours learn w/you or help you out every time you decide to go on a walk.  She walks, you try and rollerblade and she'll help.  I learned in my court.  I just kept trying every night, going in a circle until I got it.  Don't worry you'll get it.

read the whole of this link. he invented and patented some kind of paper clip - but maybe not the type that was eventually produced. Most people regard it as a myth that he invented the paper clip - except the Norwegians apparently. Read the wikipedia stuff.

The truth is no one really invented rifiling.  It is all a matter of aerodynamics.  This was first seen on the fletchings of an arrow.  The fletchings cause the arrow to twist and thus become more accurate.  \n  It took 3 brilliant gun smiths to put 2 and 2 together.  However each one of them worked separetly and could have even been considered enemies.\n\nMessrs Charles Lancaster (1820-78), William Armstrong (1810-1900) and Joseph Whitworth (1803-87). \n\nHowever, the rifling principle was discovered in 1498.  The only reason why they are considered the forefathers of rifiling is that they created cost effective ways to make the riflings in the barrels.

Things have changed a lot since rollerblades were first introduced, but I still only use the first pair I ever owned!\n\nI bought a pair of Real RollerBlades.  Now they have a lot of knockoffs, real cheap, and don't roll very well.\n\nI recommend laceup, if you can find them, because they are much more flexible as to how tight you want them to be.  And they hold to your foot from the bottom of the laces up.  Some are just buckles in three places, but they can be too loose in places.\n\nFirst, practice with protective gear.  Especially wrist guards and elbow guards.  I've seen people wear knee pads, but I've never managed to fall forward on rollerblades, so I don't wear them!\n\nI have broken my wrists, so I especially recommend the wrist guards.  If you are VERY clumsy, a helmet might be a good idea, too.\n\nSecondly, just practice rolling back and forth in a small area, until you are fairly certain you can stay vertical.  The movement on rollerblades is a bit different than skates, but you are going to push off with one foot while rolling on the other, just like skates.  \n\nOne very big difference:  With skates, the balance is more precarious from front to back.  With Blades, the tendancy is to tip from side to side.  \n\nBe prepared for a couple falls, but don't let that bother you or get you down. Just brush yourself off, and get back up!\n\nAs for the very best blades?  Go to a sporting goods store (ie NOT one of those super size discount stores) and try on all the different styles you might like.  Pay attention to comfort, just like buying shoes.  If they hurt your feet or are too hard to put on in the store, you won't be happy with them, and won't want to skate, when you get home.\n\nHappy shopping and have a great time.

Yeah! His part in Almost round three had some of the most amazing skating I have ever seen!Actually, that whole video had amazing skating(rodney, daewon, and haslam). Back to your question though..he is the most amazing freestyler i have ever seen.

I'm willing to bet the answer of that is lost to time, and probably happened pretty soon after some primitive person invented the broom. A lot of "facts lists" will say that Lloyd P. Ray did, but that's not true. He did hold a patent in the late 1800s on an improvement on the dustpan, but so do nearly 200 other folks.

just go to google and search "learanardos robot" because learanardo da vinci was the first one to create a robot

I would recommend visiting a sports equipment store. They should either sell roller blade trainers, or be able to tell you where to buy them.
