Help with balloon physics

Physics
#1

Hi there ,

I want to simulate a balloon like in real life . Having it atttached yo a rope and once the rope is cut the balloon flies away. So basically what type of physics needs to be applied inorder for the balloon to foalt always. Like the hot air float above the cold one, or like oil and water.

I tried apply linear impulse but eventually the balloon goes down.

Thank you!

Could you not set the balloons .gravityScale value to a low minus number?

eg:

balloon.gravityScale = -.25

I’ve never tried it, and I don’t even know if you can set minus values.  Unfortunately I’m at work at the moment and unable to test.
