Yes. You can make a Leyden jar with some simple stuff.

Here is a DIY Leyden jar based on an episode of MacGyver.
It's essentially just a capacitor created from water, a plastic cup and some metal. With this device, you can store charge and produce an electrical spark.

Thanks for this awesome video!, these are wicked experiments though caution is always needed.
Some tips for beginners...
1) Make sure the aluminium foil wraps around the cup/plastic bottle as smoothly as possible to prevent static discharge .
2) Use thicker wiring (3 mm) for better current flow.
3) If using a cup place foil on the inside to bump up the positive charge collection.
4) Add a pin pong ball wrapped in foil to the nail for a great discharge.
5) The more strokes with PVC pipe the bigger the voltage!
Have fun!! 😉

You need to stir the water and desolve the salt before putting a top on the cup or jar so it will produce more energy

[@madhavgautam5357]

If we simply touch the aluminum foil with the floor...will it work?

[@hayemiranda7647]

Floors are usually insulators, yeah, it should work

[@aridamangautam]

@@hayemiranda7647 This is sarcasm, right?

[@nabayanchakma2419]

Of course it will...the foil was also touching the floor in the video as u could see

[@aridamangautam]

@@nabayanchakma2419 I'd prefer that you connect a ground wire so you're absolutely sure that you've grounded the cup in incase the thing doesn't work.

I did not see the spark. You could have turned off the light in the room.

[@DuskyDaily]

But you could listen it.

[@fq638]

Is the ground wire plugged in?

[@arveen5361]

The aluminium has sharp edges,
Doesn't it let go of the charges?

[@DuskyDaily]

It's not holding the actual charge nonetheless, it suppose to be getting extra positive charge from the ground / environment to hold the negative charges in the water. And water don't have charge edges. :)

Can i use a uPVC pipe?

[@rhettallain]

yes, that should work.

Which 2 foil u have used

[@masegeangelo7073]

Aluminium foil

[@tempemail4622]

When you put the saltwater in aren't you essentially creating a batter? I'm 😕 confused

[@MichaeltLoL]

no, it's capacitor because you are holding electrical charges, not chemical energy. That's why the aluminium is separated from water by the cup

[@julianocamargo6674]

I was a bit confused also. This is a capacitor. The salted water (conductive) is one 'plate', and the aluminum foil is the other plate.

[@rachnajaiswal933]

Hello, I have a problem with my Leyden jar ... First of all I have made my Leyden jar by sticking aluminium foil both to the inside and outside and using paper clips ( but obviously that won't matter ) . The thing is that whenever I try to charge a Leyden jar I hear a crackling sound... But u believe its not supposed to be like that right ? I mean , when we try to discharge the jar then we hear a sound... So why are things working oppositely for me ?! Plz help...

[@rhettallain]

the cracking sound might be a spark. If your two metal foils are super close to each other, the charge could make a voltage high enough to produce a spark and discharge the jar.

[@rachnajaiswal933]

@@rhettallain so what should I do to prevent the thing ? I repeat that I'm getting a crackling sound when I *try to charge the jar* , plz tell

[@rhettallain]

@@rachnajaiswal933 maybe use a thicker jar? Make sure the aluminum foil doesn't go all the way to the top edge? It might be something with the paper clips - try taking those off

[@Rabiaemad1234]

I am having the same problem too and the top ball is attracting to the pvc pipe

[@koenvandemoortel2206]

You cheated with this mysterious "device"... What was that?

[@DuskyDaily]

That was just an electrostatic generator, probably a van de graff. It's just rubbing to grab electors off of a material. You can rub a PVC pipe with a towel to do the same thing.

[@allinonechannel6284]

I can make 30kv spark

Wouldn't it be nice if he pronounced "al-u-min-i-um" properly with its five syllables? Lol!

Do you know what an accent is?

[@tpxchallenger]

He is using North American pronunciation. It took my father decades after we emigrated to pronounce al-u-min-um instead of al-u-min-i-um.
