    Balloon with minimal displacement

    Thanks, @btrueblood. Tie points & ribbing are great insight. Minimal displacement tolerated but not to degree it feels like a bounce-house when people walk across it. It's important the shape be dynamic between two states (deflated and inflated) so I imagine air is my only option (the BEST...

    Balloon with minimal displacement

    Hello--can anyone offer insight into designing a balloon--essentially a thin air mattress--that when fully inflated will minimize or even prevent displacement if a person, say 250 lbs, walked across it? What PSI might be required? Balloon materials and wall thickness have yet to be determined...
