Here is an end Saber spark test. 3 different versions, first clip regular speed and second at half speed to see the difference. Let me know your thoughts. Thanks to @skenera for helping with colour correction.
The idea is to give Rey a reason for burying the Sabers after the battle with Palpatine.
V1 No blue puff of smoke
V2 Hard blue smoke
V3 Softer blue smoke
