Actually using hydrogen is very safe. We launched 10 balloons at GPSL last year and the year before that and all were using hydrogen. Walmart helium tanks are manufactured by BalloonTime. They have 8.9 or 14.9 cubic foot of helium inside depending on whether you use the standard or jumbo size tanks (about $25 to $40 each tank). Enough for 3 pico balloons (36-inch Mylar foil balloons) but it would take a lot of those canisters to fly a large latex balloon which would be more expensive than a large tank even with the crazy price gouging they do to private individuals at the big gas supply houses. The other drawback to BalloonTime canisters is that about a year or so ago they started to do a "Specially Formulated blend that won't affect performance". The marketing folks had to work overtime on that one. Turns out that they are now selling 80 percent pure helium instead of the 98 percent pure helium they used to sell....and of course at a higher price. I had a long chat with a manager at their factory in Columbus, Ohio who claimed it wouldn't affect performance at all. Nice to see that marketing folks can change the gas laws :-( They won't consider doing a special run of pure helium either.
