Another video of what I think is the sodium element which burns orange first before turning yellow in the last few moments right before all the crystals are burnt.
This element giving out bright green light when ignited is of course copper :) it is so pretty.
In this video, we ignited copper and sodium together. If the video quality is better there can be seen more clearly bright green flame and orange turning to yellow flame burning alongside each other.
Demonstration by Miss Tan! Aerosol sprays are used to spray the dissolved crystals of the elements into the fire. Elements demonstrated include potassium, calcium and copper.
Here the elements are put into a bowl and fire set to it. The colours are not as obvious however, due to the fact that alcohol is needed to keep the fire burning, and alcohol itself gives out a blue flame when burnt.
