Winterize your Home with Used Bicycle Tubes

I got a bit creative yesterday.  Cold air rushes through the bottom of the back sliding door with the force of a squalling gale.  I happened to have the metal piece hanging around which already had holes in it.  So after cleaning the tube, I cut it open, sliced it down to size and attached it to the metal piece with screws and bolts to add weight to it.  Then I used some left over double sided tape from Frost King to attach it to the door.  It does the job pretty well.
