Parker, my 9 year old son, is into Origami right now.  I think that's great.  I remember helping him make an Origami water bomb/balloon.

But, I was watching some more TED talks today and came across this.  Parker doesn't care for math too much.  He is incredibly smart, gift in many ways.  But, math is not anything he seems to ever care for.  Maybe at some point, I'm not sure when yet, I can get him to watch this 18 minute video that really shows how math and origami come together to do some really amazing things....like how the water bomb design can be used to create a cardiac stent that could save someones life.

Check out the video.  If the video player has problems, just follow the link below.
