Lightning #3

Looking almost like something you'd expect in a sci-fi movie, the lightning produced is staggeringly focussed and direct.

On peux m'expliquer pourquoi au début de la vidéo ya une lumiere qui monte au ciel . . . Et apres un eclaire parfait qui décend la ou le ... Je pense le feux d'artifice est parti?

@niina13013 My French is not very good, so apologies for using English. If anyone's good at translating, feel free. The start of the video shows a rocket carrying a wire being fired into the clouds. The light is from the rocket exhaust. When the wire reaches the clouds, the electrical charge in the clouds travels down the wire, creating the descending glow. So if I understand the question correctly, the answer is yes.

what needed to do this?

a sugar rocket good for this? with some copper

@MakaronyHacker What you need is to hit the thunder clouds. A sugar rocket should work, if the cloud layer is low enough AND the rocket has the lifting power necessary to get there. There's no rule that says you have to start from a specific height, so firing from the side of a hill (remember to fire straight up, use a spirit level to ensure this) should be fine. It might be good to experiment with thunderclouds trapped by hills versus free-moving ones, as I don't know anyone's done that work.

It's all cool and stuff until you realize you're holding the launcher control. Which is connected via wires.

@needleonthevinyl How many amps is the fuse on those wires?

[PJDooWop]

That wasn't fireworks.. That was a rocket shot into a cloud. Scientists have been doing this for at least 20 years. They'll tie 2,000+ feet of copper wire to the back of the rocket and ground it hoping to have lightning follow the line.

they bull up a metal wire.

This is how we'll solve the energy crisis.

@2206411411 Well, my French isn't very good either, but I think first she(?) asked WHY there is the light traveling upwards (so the answer to that can't be "Yes" =D) and then something about fireworks. Which is not it according to your response. ;)

this is a tecnique used called "lightning seeding" it works by giving the lightning a sure way to an earth ground via a wire attached to the wire, the other way is to shoot a HP Co2 lazer in to the clouds causing strings of ions making the air more conductive, its pretty cool but not si-fi.

@niina13013 c pas un feu dartifice c'est une boule de cuivre attachée a un fil de cuivre qui est envoyée en lair et le courant passe dans le fil d'ou l'eclair artificiel

DAMN NATURE!! YOU SCARY

[90999999999999999990]

@niina13013 enfaite jcrois que c'est eu meme qui long fait avec le truc qui par vers le haut on entend yeeeaaa parce qui long reussi

[batcoh2]

00:06 nice sound

[cril1001001]

I can't imagine how awesome it must feel to cause your own real lightning strike. This is seriously cool as hell
