MATERIALS:43 concert bells, salt clappers and cows.
43 concert bells, one for each note in the song When The Saints Come Marching In, are hung along a cattle feeding trough. The bell's clappers are made of salt; so that when the cows lick them, the bells play their respective note. There is an impossibly small chance, that some day, the cows will play the notes in the right sequence, and thus the song.
Note: Unlike regular bells, concert bells are tuned to play specific notes
