Gallium

Gallium was the element that was most likely intended for magic tricks. Gallium is a solid, much like chocolate, despite the fact that it seems to be any other silvery metal at ambient temperature. Once it starts to warm up, everything is over. Just below 30 degrees Celsius, or a warm summer day but not scorching, is the melting point of gallium. You may liquefy the metal in your palm since your body temperature is 37 degrees Celsius. YouTube movies showing people stirring boiling liquid with gallium spoons that instantly melt away have been produced as a result of this.

Despite having a low melting point, gallium won't boil until it reaches a temperature of 2,229 °C. Because of this, high temperature thermometers can really benefit from it. It's one of those peculiar substances that has no function at all in biology. Absolutely no plant or animal life need it. Nevertheless, it can be helpful because it appears to be effective in battling some cancers.
