This is why today, most liquid metal thermometers use the non-toxic alloy Galinstan instead of mercury. It's an 'eutectic alloy', which is actually a really interesting physical phenomenon where a specific mixture of metals can have a lower melting point than any of it's constituent metals - the main ingredient Gallium becomes liquid at 29°C/85°F, but the addition of Indium and Tin lowers the alloy's melting point to -19°C/-2°F, making it liquid far below room temperature.
