How Microwaving Grapes Makes Plasma

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they touch. This creates heating, sparks, and plasma, which is further fed with energy directly by the microwaves.

Huge thanks to Hamza Khattak, Prof. Pablo Bianucci and Prof. Aaron Slepkov (unavailable for the call) for chatting to me and helping me understand the physics of this cool phenomenon.

Make Plasma With Grapes In The Microwave!

When a grape is cut nearly in half and placed in a microwave, plasma is produced. Please use caution if attempting this experiment: don't leave the microwave on for too long, make sure the area is well ventilated, and stand back. Remember the contents will be very hot afterwards.

Plasma from grapes in microwave oven

Supplementary videos from the paper Linking plasma formation in grapes to microwave resonances of aqueous dimers authored by Hamza K. Khattak, Pablo Bianucci, and Aaron D. Slepkov, published in PNAS

Movie S1. Video of plasma created by irradiation of grape hemispheres in a commercial microwave oven in the traditional manner.

Movie S2. Video of plasma created by irradiation in a commercial microwave oven of whole (uncut) grapes forming a dimer on a watch glass.

Movie S3. Video of plasma created by irradiation in a commercial microwave oven of hydrogel beads forming a dimer on a watch glass. The beads were first hydrated in de-ionized water and then soaked in a weak NaCl brine for one minute before filming.

Movie S4. High-speed video of grape dimer and hydrogel dimer irradiated in a commercial microwave oven, both igniting plasma and undergoing mechanical oscillations. Grape dimer filmed at 1000 fps; hydrogel dimer filmed at 2000 fps.

Movie S5. Live thermal imaging of large and small individual water beads (0:16-1:10), and a water bead dimer (1:15-2:15) during microwave irradiation.

The microwave plasma mystery

Sometime last year, I got really interested in microwave plasma, which can be made from a lot of things like lit matches, aluminum foil or just some grapes. However, when I went searching for more info about it, I really couldn't find much of anything. There was also no explanation as to why it was yellow every time, regardless of what it was made from.

So, I decided to investigate this a little bit and try to get to the bottom of it.

Grape in Microwave = PLASMA!! - Part 1

Cut a grape in half, then in half again so the 2 1/4s are still attached, take the glass tray in the microwave out and then set the grape in the center of the microwave somewhere and start the microwave! Cup over the grape is optional just to catch the plasma and hold it. Careful, too long and the cup (or bowl) will explode

What happens to two grape berries in the microwave? Microwaving grapes make plasma! Amazing!

Before you go home to experiment, you have to take the risk of destroying your oven. Or seven, as the researchers did before it found the right answer to this question.

It has long been thought that grapes generate plasma because the microwave energy loads the electrolytes inside the grain. Which is right. But as the spectacular phenomenon takes place, it is not important that the beans remain stuck at the end of the protective cover to act as a bridge, the three engineers who developed the study claim. They have shown that grapes can create plasma even if they are left whole, three millimeters away.

The bark of the berries is of no relevance, apparently, only the water content.

At the moment they are bombarded by energy, the beans approach each other and an electromagnetic field is formed at the point of contact. This is how the plasma jet appears.

Microwaving Grapes Makes Plasma + SloMo

Step 1 - cut the crap in half
Step 2 - place it inside two microwave save, clear pyrex dish/bowls
Step 3 - microwave for 30s
* Caution - this is an experiment for adults only, this involves plasma, the 4th state of matter, yes, it can be very hot.

What? It's true. Thanks to ifuckinglovescience.com and veritasium for the inspiration to do it myself! Totally exciting.

Science Team! We made the fourth state of matter (nbd) with a microwave and some incense I got a home good store. I will admit, this one freaked me out a bit. The sounds and brightness was incredible

This actually ended up looking like a possessed microwave, happy halloween everyone!

Bombarding a carbon source with microwaves strips the carbon of electrons. These electrons pool at the top of our pyrex cup. While they are in their excited state we see this a very bright glowing plasma!

Making Plasma, Microwaving grapes --- SMS#2

Welcome back to Slow Motion Saturday! This week is about electricity and plasma.
So out first suggestion come from user xZxDerpDragonxZx.. He wants me to DO SOMETHING WITH PLASMA. well thats a pretty general suggestion but i know just the thing *slam microwave transformer* Its a microwave oven transformer. You've seen me use this in my other videos like woodturning with electricity, or cooking an egg with high voltage. Plasma, like solid liquid and gas is considered a state of matter. Plasma is ionized gas, and can be created by applying energy to a gas, like electromagnetic or electrical energy like this transformer.

As you can see it puts out an extremely powerful arc of electricity, But its 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 electrical outlets. the alternating current reverses direction 60 times per second, which causes the flicker. The blue light in the center is the electrical arc, its so hot its turning the surrounding air into plasma


The next suggestions comes from viewer lanceipod7 he asks if I can throw a grape in the microwave, and I would be happy to, because I've actually never done this before. All I needed to do was cut the top off a grape, and split it down the middle, but carefully leaving the two halves connected.

I read all my comments, but sometimes I miss a few! If you need help with a project you are welcome to email me :)

On my Facebook, G+, and Twitter page I post questions, polls, and sneak peeks into my next video. Im always looking for my fans input!
