But Legos float
- gerdesj 5y agoPretty sure they don't if you expel all trapped air. Its this stuff: https://en.wikipedia.org/wiki/Acrylonitrile_butadiene_styrene https://en.wikipedia.org/wiki/Acrylonitrile_butadiene_styren... which has a density > 1 x 10^3 kg/m^3 ie 1 g per cc. Water is slightly less than 1. Lego sinks.

- gweinberg 5y agoBet they float in salt water.
- gerdesj 5y agoI 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 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.
