Learn about the science of acid-base reactions and buoyancy with the Diving Submarine.
Just fill your Submarine with a mixture of bicarbonate of soda and citric acid which in the presence of water reacts to cause the submarine to float!
Please note: Instructions are included. Sodium citrate is not hazardous or irritating so feel free to splash around in the bath with your submarine. Just take care to avoid skin or eye contact with the fuel powder.
