A movie that plunges alkali metal into a large amount of water and makes it violently explode

The group of elements belonging to the leftmost side in the periodic table is called the group 1 element and corresponds to hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. Among these, alkali metals excluding hydrogen are called alkali metals, but there are ones that react vigorously with water as these properties. There was a movie that tried what happens when putting these alkali metal in the bathtub. Of course, a big explosion happens as expected.

The playback of the movie is from the following.

Initially I am starting with reacting lithium with a small amount of water in a dish. As lithium, sodium and potassium progress, the reaction becomes more intense. And rubbish into the bathtub. It is interesting that the person of the investigator flurries and escape at the moment of putting in the bathtub. However, there are things that only escape.

Other movies that reacted alkali metal and water are also listed below.
