we finally finished one of our vacation crafts that we started. the idea for these shakers comes from an ipod app from Disney Family Craft Finder - such a fun app to help you think of new ideas for kids crafting. we found some forked branches on vacation and alex painted them green. i then sawed them off - and actually i still need to sand paper down the ends to make them smoother. my husband put holes in bottles by hammering a nail thru them and then flattening them with a hammer. alex and i strung the bottle caps and pop tabs to the branches with some thin crafting wire. i didn't want any loose wires hanging out and wanted to help secure the wire so i went over that part with some gorilla glue - that wire is not budging now. they turned out pretty well and actually make some pretty good noise - if we had boiled the bottle caps and removed the rubber insides it would have been a stronger noise but we did not go that far and they still make some nice sounds.
