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!
