Alkali metals are a group of soft, low-density, low-melting, highly reactive metallic elements, including lithium, sodium, potassium, rubidium, cesium, and francium. They form alkalies when they combine with other elements. Because their atoms have only one electron in the outermost shell, they are very reactive chemically. They react rapidly, even violently, with water.

That last one, what a shocker! Had I been in the room, i would have screamed, most likely. Almost did it just watching here.
Simply amazing, thanks for sharing this.
Francium is a radioactive element with a half-life of only 22 minutes. Collecting sufficient francium for a similar experiment would be extremely difficult.
