Elemental Burning II
Elements can burn, some burn brightly, some burn beautifully, and some transform into weird shapes after burning. As a sequel to Elemental Burning, here we show the combustion of 4 more elements: lithium, hydrogen, iron, and potassium.
Combustion of lithium in the air
Combustion of iron powder in the air
Combustion of hydrogen gas in the air (hydrogen generated by the reaction between lithium and water)
Combustion of potassium in the air
