Gallium Melts In Your Hand
Gallium is a chemical element with symbol Ga and atomic number 31 on the periodic table of elements. The best part is that Gallium is a non-toxic metal that easily melts in your hand!
Because Gallium has a melting point of 85 degrees Fahrenheit, which is 13 degrees lower than the human's body temperature, it will melt if you hold it. By placing the Gallium back on a cool surface it will harden and become solid once again.
Although it is non-toxic, it is recommended you handle the Gallium with gloves as it is sticky and for some people can be a skin-irritant.
This sample of Gallium is 20 grams, which measures about the site of an American USD 50 cent piece. Gallium is a great gift for the guy that loves science. If you'd like to buy in bulk, you can get 50 grams here or select multiple items during checkout.
