A Rare Opportunity to Watch an Electrical Tree Grow in Slow Motion

You ’ll often see electric trees after lightning strikes . you may descry them in sand , in insulation , and even on very luckless hoi polloi ’s consistency . in general , they form too fast for us to see them arise , which is why this video is so interesting .

Electrical trees , also known as Lichtenberg figures , generally form very quickly . Here ’s a luck to see one configuration in slow motion . keep an eye on as cracks creep across an insulator , crystalise the path for a flash of electrical energy . Here we see crack in insulating material grow slowly , building up to a meter when electricity can shoot from one end of the fig to the other .

These trees form in detachment when it is loaded up with electrons . Because the cloth is a good dielectric those negatron have trouble go through it , meaning the entire structure is buzzing with negatron that ca n’t go anywhere . What ordinarily amaze them moving , and makes the material body appear in the insularism , is a offer forming in the insulation . ( Often , in television , you ’ll see people wiretap on the insulation with a nail to start a crack forming . ) The first wisecrack allow flaw in the insulation and a channel for the electron . Their movement opens up more crack , and the drift of the electrons burns the lightning approach pattern into the figure .

Here we see the process going in sluggish motion , and crevice slowly progress up . At the end , we see a current move from one side of the nonconductor to the other , through the cracks .
