Materials Required:—

A fowl's merrythought or wishbone, a small slip of thin wood, a piece of strong string, penknife.

This is made of a fowl's wishbone or merrythought. Tie across from end to end of the bone a loop of string, and into this insert the end of a thin piece of wood about four inches long and three quarters of an inch wide. Slip this in till the string is about the middle, then turn it round several times till the string is twisted fairly tight without bending the ends of the bone too much. Now slip the wooden strip along till the string is about an inch from the end of it and let it go. The twisting of the string will bring the wood down against the angle of the bone with a smart clap.
