Homemade Maracas

Today I used an empty ketchup bottle, some Discount School Supply Bio-Color paint, and Mod Podge to make a maraca. I taped the lid on with blue duct tape. Now granted, my painting job won't win any awards (LOL), but I don't think it turned out bad. I'm not sure if plain tempera paint would work, but acrylic paint would. I painted it, let the paint dry, then covered it with Mod Podge to seal it. After it dried, I put some rice inside (you could use anything: beans, pennies, etc.), put the lid on, and taped it shut.
