A worker at Walt Disney World is “recovering” after being injured by a 400-lb (180kg) runaway fake boulder prop in an incident that was caught on video, the Florida theme park confirmed.
The incident took place at the Indiana Jones Epic Stunt Spectacular! during a live recreation of a famous scene from the film.
Video shows the boulder rolling towards the audience as a staff member jumps into its path, preventing it from reaching the crowd.
While your username might imply some sort of expertise, I looked at weights for a ball of this size and could get below like 288 kilos no matter what the ball is made out of.
Even just a rubber ball of 1cm thick rubber and filled with air would weigh closer to half a ton.
idunno. this one is 13 lbs.

Idk what you’ve linked, but remember it can’t just be a big thing you fill with air, it also has to be able to roll without deforming.
Specially since air also has mass and weight
