Kid's Art Craft -- Penguins from recycled bottles and bottle caps

Need a kid's activity? Want one that's winter-related using recycled stuff from around the house?  Family Fun magazine has some usable stuff; here's a good one:  http://familyfun.go.com/crafts/penguin-lawn-decoration-802301/ 

You take 2-litre and smaller empty soda bottles, splash black paint INSIDE and shake it up (always fun to shake), let it dry more or less, then add some sand to make them stand up, and finally decorate as penguins.  Ours did NOT come out as perfect as the magazine's (big surprise) mostly because of the flaking white tummy paint.  I'm told that if we had sanded the outside first the white paint would have adhered.  Regardless, they are perfectly imperfect.  I especially love the wobbly eye on the little one.  We used construction paper for the feet, beaks, and wings (as opposed to the more expensive foam stuff the magazine used).  The hats are bottle tops from a liquid laundry detergent container.  The scarves are cut pieces of fleece from old scarves.  The result is a fun piece of winter.
