It is believed that long-long ago, someone happened to cut an old bicycle inner tube for tying certain object, and then others found it very useful and convenient even though it was not as elastic as today's rubber band. Eventually commercial production commenced with right formulation by business minded people.

Main material is "rubber", usually natural rubber, but some types of synthetic rubber are also used to obtain certain specific quality depending on the application. Besides, fillers such as calcium carbonate, carbon black, clay and additives like sulfur, stearic acid, zinc oxide, wax, oil, accelerators are mixed into rubber as ingredients.

See the Rubber Band Effect in a Form sample from Simon Bond at C# Corner that implements this sizing technique. Be sure to read the article Debugging "Rubber Band Effect" , where Zhanbo Sun suggests a modification that handles a problem he spotted... See similar questions...

The rubber band at the tip is used to help keep the dreads together when they are new and it helps the tip lock up once the dreads are tight. See similar questions...

The unspoken objective of this question is, "How can I render something, then erase it without disturbing what has already been rendered?" One way is to use overlay planes. You draw the rubber-band lines into the overlay planes, then clear the overlay planes. The contents of the main framebuffer isn't disturbed. The disadvantage of this approach is that OpenGL devices don't widely support overlay planes. The other approach is to render with logic op enabled and set to XOR mode. See similar questions...

Feed the compound into a machine called "extruder" to make into tube form called "tubing", just like making Italian Macaroni. Put a round pipe into each tubing, and heat up in pressurized steam tank. This pipe gives round shape to rubber band and this heating process is called "vulcanization". Remove the pipe and cut the vulcanized tubing into "rings" using high speed cutter. These rings are "rubber bands". Rubber bands are well washed and dried. See similar questions...

Products made of natural rubber are, in general, aged faster by exposure to heat, air and sun light. Therefore, rubber bands should be packed, preferably in air tight bag or container, and stored in cool and dark place for securing longer life. See similar questions...

If it is just a regular rubber band then you should just leave it there until it falls off, but if it is one of those super Scunci elastics then it will never fall off, you should take it off after three months. See similar questions...

When I was four. My older cousin had one, and he was the coolest, so I had to have one too. My mom actually started it for me because I wasn't able to wrap the bands around themselves. I don't even take breaks on holidays. C'mon. It's just a part-time thing. At this point, I only add to it when I'm on the phone with someone who won't shut up. I have one of those hands-free telemarketer headsets. See similar questions...

Not even close. The biggest ball in the world weighs over two tons. The guy who made it lives in the country and keeps it in a garage. See similar questions...

Rubber-banding of tab elements is done by starting the process with the mouse on the primary form (off the tab) and dragging across the tab and the elements desired. This action selects the desired elements AND the tab group itself. Before working with the layout elements, you must remove the tab group from the selection. This is done by holding down the Shift key and clicking on the tab group at the bottom, to the right of the last tab page label. See similar questions...

Flower essences were first developed in the 1930's by the English physician, Edward Bach. Dr. Bach was a classically trained physician who became a pioneer in understanding the relationship of emotions to the health of body and mind. Today we call this the "body/mind connection." You can also use the tongue-twister, "psychoneuroimmunology." He observed that many physical diseases could be directly related to a person's mental attitude. See similar questions...

Dr. Benjamin Gavish, InterCure's Founder and Chief Scientific Officer, patented and developed a fundamental method of affecting biological rhythms and respiration with external rhythms such as melody, which led to the development of RESPeRATE, the company's first product. See similar questions...

Aerogel was first made in the 1930s by Samuel S. Kistler, who obtained several patents for making a variety of aerogel, including silica, alumina, chromia, tin and carbon. See similar questions...

Rubber bands or elastics contribute a lot to straighter teeth. They are marvels of physics. Attached to your braces, elastics exert the energy force that creates the right amount of pressure to move teeth. It's important to wear your elastics all the time and change them every day so the force is constant which the teeth like. As for bouncing an elastic off someone across the room, it will happen (don't worry, your aim will improve). See similar questions...

We really can't help you there. Sorry. But any local office supply store may make one for you. There are also many online custom stamp makers on the Internet. See similar questions...

Because they may stick together. If any adhesive is outside the flap and still wet, which is possible whether the letters are hand-sealed or done by machine, the pressure of the rubber band will cause it to stick to the next envelope. See similar questions...

The Imaging Tech display must depict the published theme in the rules for that year. The judges must not have thought your pictures depicted the theme well. Try, try again! Yes, the rules have been refined to make our members think a little harder! The original idea of the contest was for students to build a simple "robotic arm" type of mechanism. Instead, smart TSA students took the rules to the limits, and used simple rakes and hoes to pull the balls toward them. See similar questions...
