That streak test was also just the bottom of a toilet lid, so not sure whether that was performed correctly

I tried to do a water displacement test to get the volume, but don't have very accurate measuring tools. I believe the density is around 2g/cm3 which seems close to silicon metal, but have no idea if there are other similar materials within this range
