I have pictures of what I called "treasure buddies". These were animals made
from bottles who's heads screwed off in order to hide your "treasures". We
used all types of plastic (they're lighter) bottles which the kids brought
in. Kids made snakes, crabs, dogs, cats, dragons, bats etc... It was a great
lesson! If you would like to see pics- let me know and i could send as an
attachment.
