Experiment with sodium bicarbonate and vinegar Increases the volume
All the alkali metals react with water to produce elementary hydrogen and the corresponding alkali hydroxides. The reactivity increases with increasing periodic number. The reactions2 Na + 2 H2O ----> 2 NaOH + H22 K + 2 H2O ----> 2 KOH + H2I got lucky with this sodium reaction, I have never had such a perfect explosion.

A small piece of sodium metal is ignited and placed in a flask containing chlorine gas. The reaction produces a white smoke of sodium chloride(table salt).
Bicarbonate has beneficial effects on health
Bicarbonate is a major element in our body. Secreted by the stomach, it is necessary for digestion. When ingested, for example, with mineral water, it helps buffer lactic acid generated during exercise and also reduces the acidity of dietary components. Finally, it has a prevention effect on dental cavities.
Bicarbonate is present in all body fluids (see table) and organs and plays a major role in the acid-base balances in the human body. The first organ where food, beverages and water stay in our body is the stomach. The mucus membrane of the human stomach has 30 million glands which produce gastric juice containing not only acids, but also bicarbonate. The flow of bicarbonate in the stomach amounts from 400 µmol per hour (24.4 mg/h) for a basal output to 1,200 µmol per hour (73.2 mg/h) for a maximal output. Thus at least half a gram of bicarbonate is secreted daily in our stomach. This rate of gastric bicarbonate secretion is 2-10% of the maximum rate of acid secretion. In the stomach, bicarbonate participates in a mucus-bicarbonate barrier regarded as the first line of the protective and repair mechanisms. On neutralization by acid, carbon dioxide is produced from bicarbonate. A study has underlined that a dose of 6.17 g of sodium bicarbonate rapidly leaves the stomach with the liquid phase of the meal.
