I don't bath in salt water so never tested that.

According to WP: "The density of surface seawater ranges from about 1020 to 1029 kg/m3"

According to WP: ABS is 1.060–1.080 g/cm3

Lego sinks in seawater.

If you saturate a beaker of water with salt then lets go here for some results because I can't be arsed to go back to school: https://en.wikipedia.org/wiki/Saline_water

Roughly 1.193 g/cm3 which is more dense than ABS so Lego will float in salt (NaCl) saturated water.
