Rubber band gun Rubber band gun A rubber band gun, often abbreviated to RBG, is a toy gun used to fire one or more rubber bands (or "elastic bands"). Rubber band guns are often used in live-action games such as Assassins, in which they are common and popular toy weapons. They are also common in offices and classrooms. Rubber band guns have been popular toys that date back to the invention of rubber bands, which were patented in England on March 17, 1845 by Stephen Perry. This is the simplest form of rubber band gun. Its firing mechanism consists solely of a clothespin.
Smart rubber substance together, allowing the recovery of a continuous hydrogen bonding network. Smart rubber will recover its original mechanical strength within several hours of being split and then subsequently recombined. Residual hydrogen bond donors and acceptors responsible for the self-healing properties of the elastomer remain unpaired until the newly exposed surface comes in contact with another complimentary surface, allowing formation of new intermolecular hydrogen bonds. When compared to rubber, which is covalently cross-linked, smart rubber cannot continually hold mechanical stress without undergoing gradual plastic deformation, and strain recovery is typically slow. Smart rubber Smart rubber is a polymeric material that is
