The sodium reacts most vigorously with the nitric acid, producing a flame and smoke. The sodium also reacts pretty strongly with the weaker concentration of hydrochloric acid. The demonstration shown ...

Since one might attribute the widening to the known effects of the magnetic field upon the flame, which would cause an alteration in the density and temperature of the sodium vapour, I had resort ...
