Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour.

When it rains a lot, the river runs slower, causing its damming, thus increasing the water level of the river Olho D'Água. Despite the flood, on the day the video was recorded the waters of the river Olho D'Agua remained crystal clear due to their conserved ciliary forest and being inside a Private Reserve of Natural Heritage - RPPN, a type of Conservation Unit. This was a rare episode, and by the end of the day the river had returned to its normal level.
