Reaction of lithium with water, this time as a small compact metal piece instead of powder. Hydrogen is produced that does not self ignite, so it had to be ignited. It burns with a red flame characteristic of lithium ions. Lithium hydroxide is formed in solution, which is strongly alkaline but is less soluble than other alkali-metal hydroxides. In general, lithium is the least reactive of all the alkali-metals.
Sorry for the image quality. For a better demo, see Dnn87's lithium and water.
