Being described is the simple laboratory facility, simulating the process of loss of buoyancy of a ship in case of a sudden release of gas bubbles from the sea bottom. Bubble generation method is based on electrochemical reaction, when current is let through the aqueous solution of NaHCO3resulting in CO2 bubbles release. It was demonstrated, that the dynamics of shipwreck can be recorded and studied in detail. The device can be used for practical workshop training purposes in universities and marine academies.
