Make a paper airplane out of used paper. 

Here is a fun summer Earth-saving activity.  You can reuse some of that scrap computer paper or even news and magazine pages to make paper airplanes.  Have a contest with your friends to see whose plane flies the greatest distance. 

Check out ten different paper airplanes here http://www.10paperairplanes.com/

Be sure to recycle the paper when you are finished having fun.
