You could use Pringles (the chips that come in tubes) containers to make money banks.
Cover them to decorate and cut a slit in the plastic lid.
There are snack-size Pringles' containers now which would be the perfect size (the normal ones might be too tall).
Use glue and wallpaper to cover the sides, and then cut out shapes from other colours of wallpaper to glue on a cut-out picture, or the letters for World Friendship Fund.
