For example, a red apple is reflecting red light and absorbing all other colors of light. The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
First Velcro was made out of cotton by George De Mestral, although this cotton wasn't as strong as De Mestral had thought it to be. Today Velcro is made of various materials ranging from Nylon and pollyester to stainless steel and Synthetic fibers!
Answer Wiki. In the news a few years ago was quiet Velcro, an invention by Leonard Duffy that he calls a Slidingly engaging fastener. The product is self-mating, as the two halves are the same. Arrays of 'mushrooms' fit into place, and lock by sliding into position. It looks like the product has some play when shear is applied (it has to 'slide' into an engaged position), but once in that position it resists tension as well.
