My kids and I like kites.
We had a pair of kites, some very long string, and we live just by the desert -- so wind is strong and steady.
But flying kites you buy is not as fun as flying kites you build.
So here's an instructable for creatign your very own small kite, which flies very well.
Note: After a number of uses these kites wear out, so once every few weeks you have to buld them again. More fun!!
