Does anybody have an idea for a homemade musical instument? - homemade maracas

I just need an idea to a working instrument could play a recognizable song. It should not be complicated, but I'm limited to my own work and found materials in my own house. I was also the song without telling my teammates what song to play it and just give me credit, if it can not recognize the song. In principle, eliminating single-string picking and maracas. All ideas and suggestions we are grateful. Thank you!
