means for dampening vibrations in a strung game racket or a spoked wheel comprising a block of flexible , thermoplastic elastomer honeycomb bonded to and sandwiched between two thermoplastic facings . the device is inserted between at least two strings of the interwoven string diaphragm of the racket , or two spokes in a spoked wheel arrangement , in such a manner as to allow the exposed honeycomb core at the sides of the device to wrap around the engaged strings or spokes and hold the device in place . the device absorbs vibrations in the strings that originate from the striking surface when a ball is struck , and vibrations in the spokes emanating from normal use of a wheel .
