A reinforcement for an expandable or foaming material is disclosed that comprises a first and a second member each having protuberances that are contacted when the first and second members are joined. The elongate tube and the bladders define an inner volume that is sealed from an ambient outside environment and filled with a combination of a highly viscous, gel-like material and a gas, whereby when one of the flexible bladders is squeezed, the highly viscous gel-like material and the gas are forced through the elongate tube thereby creating a gurgling sound. Continuous lines that correspond to the paths of the portion of the blood vessels in the image are automatically generated by bridging the discontinuities in the discontinuous lines.
