youtube, tinfoil, and monster trucks

jake really got into youtube this summer.  He watches everything you could imagine.  Monster truck races, lego movies, how to make angry bird cupcakes.  One day he got real excited about a video of a little boy and his dad using tin foil for their monster truck races.  This link could be it.  I'm not positive but, its the general idea.  For days all he wanted was pieces of tin foil.  It was all over the place.  He loved it, though.
