This seemingly magical metal literally melts in your hands.

If you hold it in a closed hand and allow it to slowly heat up, you will start noticing silver droplets of liquid Gallium form, the longer you hold it, the more the crystal melts, hold it too long and you will be left with just liquid metal in your hand.

Gallium melts at just below 30 Degrees Celsius, so it's a solid, shiny, heavy metal at room temperature and lower, but from 29.76 °C and higher it's a liquid.

Gallium is the 31st element on the Periodic Table, and in this, its purest form, it's Non Toxic, so safe to play and experiment with.


This listing is for the 4 x crystals in the photos with a combined weight of 15g


In nature, Gallium is never found as a free element and cannot be found in a substantial amount in any minerals. Rather, it exists in trace amounts in various compounds, including zinc ores and bauxite. By weight, gallium makes up about 0.0019 percent of Earth's crust, according to It is easily obtained by smelting, however, and most commercial gallium is extracted as a byproduct of aluminum and zinc production, according to Chemicool
