I can’t believe they wouldn’t even let me hold a vote among the passengers about whether to try the loop.

    You just have to go fast enough. The minimum speed keeping you from falling out of a circular loop is sqrt(gr), with gravitational acceleration g and loop radius r. 10m radius requires 36km/h, which might be suitable for a Jetski. Larger ships need bigger loops to physically fit, and consequently larger speeds. It’s quite surprising, but a monstrous 100m radius loop needs less than 120km/h.

      so mass doesn’t factor into the equation??? a Jetski made from aluminum would need the same speed as from osmium?
