What are the observations when lithium reacts with water?

When lithium reacts with water, it produces lithium hydroxide and hydrogen gas. The reaction is exothermic, releasing heat and causing the hydrogen gas to ignite, sometimes resulting in a small flame. Lithium floats on water and moves around as it reacts, often forming a ball-like shape. The overall reaction is relatively mild compared to other alkali metals, but it still demonstrates lithium's reactivity with water.
