How To Create A Fiery Plasma With A Single Grape And A Microwave

Plasma is amazing. It’s part of the ionosphere. It’s part of the sun. And you can create it in your microwave, with a grape (provided you have no further use for either the microwave or the grape.)

We’re talking plasma here, on a gigantic scale, things you won;t probably see with your own eyes. But that’s where The Backyard Scientist comes in, because he wants to bring plasma back to the people with this video showing you how to make your very own ionized gas. (But kids please don’t try this at home!)

How To Create A Fiery Plasma With A Single Grape And A MicrowaveIt’s quite simple because at home, plasma generation can be created using a microwave oven transformer. Just like a solid or a liquid, plasma is a state of matter with its own unique set of properties, and it can be produced by applying a lot of energy to a gas. You can use electromagnetic energy to achieve this, or electrical energy, which is given off by the transformer.

When you watch the video, you’ll see the transformer produce an extremely powerful arc of electricity that kinda looks like fire.

But it’s hiding a cool secret we cant see with our own eyes. At 10x slow motion we begin to see a flickering light, this is caused by the AC or alternating current that comes out of electrical outlets. The alternating current reverses direction 60 times per second, which causes the flicker. The blue light in the centre is the electrical arc, it’s so hot it’s turning the surrounding air into plasma,” says TheBackyard Scientist.


But, you know what’s more awesome? It’s making plasma by putting a grape in the microwave.

How To Create A Fiery Plasma With A Single Grape And A Microwave

Yes! Impossible but true.

You can use any type of grape for this, just cut the bottom off and slice the rest of the grape down the middle, but not all the way so the two halves are still attached. Take the rotating plate out of the microwave, pop the grape in, and cover it with a cup. The results are so much cool, especially when The Backyard Scientist slows the footage down 1,000 times so you can see what’s going on in slow mo.

Farewell, sweet grape. You did it for science.
