Create a playtime raft that really floats with just a few natural twigs from your own backyard.
Have
your kids search your backyard for twigs. Use outdoor trimmers to cut
the twigs to the same size. Using jute or hemp cord, weave the ends of
the twigs on both sides to tie them together. Attach a twig in an
upright position for the mast. Cut a sail from colorful felt. Fold the
felt in half, punch a hole in the middle, and slide it over the mast.
