How to make things float in water?

it's not in the tinker panel

@RudimentaryCheezit don't have tinker pannel ;(

i don’t play career mode, but i assume there is advanced settings in the part’s properties

@RudimentaryCheezit Is it possible to change in career mode?

buoyancy, in advanced settings

the density of the water also determines if you float

too dense water or too much buoyancy, will cause the craft to launch into the sky like a balloon you try to put underwater
