You can buy these lightweight tanks of helium at Walmart or any party supply store. They are thin-walled steel, not like the heavy gas cylinders used in welding, and only contain enough helium for about 30 balloons. On the plus side, they come with a supply of balloons and ribbon, so you're all set to entertain the kids with elements (at 75 cents a pop, so to speak).
