      Why mess around with helium. Get a glass bottle, fill
      it halfway up with lye, stuff some crumpled up
      aluminum foil into it into the lye. then put a balloon
      over the end and watch it fill up with hydrogen which
      is half the weight (twice the lifting force) of

      Watch out, the bottle will get hot. Don't use a metal
      or plastic bottle.
