Van De Graaff Generators Small and LargeThe Van de Graaff generator is a device that creates and accumulates a significant amount of static electricity on a metal sphere. Its components include a base, an insulating column, a large metal sphere, and a smaller discharge sphere on an insulated handle connected to an earthed source.

The Van de Graaff generator is a device that creates and accumulates a significant amount of static electricity on a metal sphere. Its components include a base, an insulating column, a large metal sphere, and a smaller discharge sphere on an insulated handle connected to an earthed source. A nylon pulley in the base drives a rubber or latex belt over a metal pulley inside the top sphere.

The belt transfers negative ions to the earthed comb at the lower pulley, while the top metal pulley and comb collect and transfer positive charge to the dome. This process results in high voltage, low current, and eventual discharge to the earth through sparks to the discharge sphere.

When operating under optimal conditions, this generator can generate 400,000 volts and a short circuit current of 20 micro-amps. The spark created has a voltage of about 30,000 volts per centimetre, making it useful for demonstrating static electricity and electric fields.

Good wine opener, not great
Color: Silver, Number of Items: 1
Definitely doesn’t feel as robust as other openers I’ve used. Takes a bit for the teeth to catch and you have to ensure it’s all the way in before pulling the cork out. Still gets the job done though

great addition to your wine collection
Color: Silver, Number of Items: 1
The wine opener works just fine. I had one like this before but it was difficult to get the cork out. This one is much easier and it also looks good as well. The handles add a nice touch.

I had had it with cheaply functioning wine bottle openers!
Color: Silver, Number of Items: 1
I like a manually functioning wine bottle opener. This one is smooth and easy to use and I didn't feel like I would cut my finger when removing the cork from the opener. Would definitely recommend!
