  • With point 5 of lessons learned, according to the eBay seller you want to use the minimal amount of gas at lift-off to get maximum altitude. It allows the balloon to expand more (as air pressure gets less) before exploding. If you start with too much it has nowhere to go!

    Great project, look forward to further successes!
