From Santiago de Compostela: two scallop shells ( the symbol of St James -Sant Iago -) Hold one in left hand and run the rim of the other against it plus chink-chink in between: very effective, but when you use new shells expect bits to come flying off like dandruff everywhere!
I also remember doing Britten's "Noye's Fludde" at school: we all had to take teacups in which were then tested for pitch, and the suitable ones strung up in a line and gently struck to represent raindrops.
WYSIWYG: I have the Scottish version of your shaker: a tube which originally housed shortbreads. I hit it too hard in a session last summer and the sellotape holding the top on popped off and everyone got showered with rice!
