Description:
The 3000 gram balloon is the ultimate workhorse for heavy payloads, and is responsible for setting multiple world records for exceptional feats of high altitude ballooning. In 2016, Third Man Records, the Nashville label founded by Jack White, launched a gold-plated vinyl copy of Carl Sagan's "A Glorious Dawn" actively playing on a turntable lifted by a Kaymont 3000 gram balloon to 94,000 ft. The payload was 25lbs. When properly launched, our 3000g balloon with a 4-8lb payload will reach an estimated 115,000- 125,000 ft (35052- 38100 m) burst altitude. For heavier payloads, use the Kaymont Prediction Tools & Burst Calculator (leaving Scientific Sales.)
