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.

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.
How to Make Plasma in Your Microwave ... With a Grape
You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.
We're conducting a survey of our viewers! If you have time, please give us feedback:

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.

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.
☢ Microwave Plasma : AWESOME experiment
Before you try this with your microwave, just realize it can completely ruin it. So make sure you are careful and don't so something that could cost you a new microwave. We heard about making plasma with a microwave and we thought we'd try it. It was allot more awesome in person and I still want to try it with a grape. The video's of people making plasma from a grape sound fun too.
And before anyone comments on how we didn't clean the microwave, yes we know, and we will make sure it is clean next time.
I didn't give a very descriptive description of plasma so if you still dont know what it is you should research more about it. Basically it is Extremely hot!
This is only the second science video we've do, so bare with us. We are still learning, and are in the process of getting more equipment to use and be able to do more experiments.
If you have ideas of awesome experiments, PLEASE comment!!!! It really helps. We are just having trouble coming up with cool things to do that you haven't seen one hundred times.
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.
Don't Try This at Home - 2 - Grape Microwave Plasma
Grape Plasma In Microwave
Grape + Microwave = Plasma
Whole grapes in the microwave oven
It is known that a grape cut in half with a skin bridge will produce plasma in a standard microwave oven. We show that as long as grapes are in contact, whole unadulterated grapes will also produce plasma.
How Microwaving Grapes Makes Plasma and Destroys Your Microwave - Not a Safe Experiment!
See why doing the grape plasma experiment is amazing and destructive at the same time. This is a real experiment gone awry. One grape destroyed my microwave and the video proves it. There were no tricks.
grape in the microwave plasma gone wrong
Don't try this for more than 5 seconds at a time if you value your glass cups.
I made this with pocket video

Alot of grapes were put in the microwave to make sparks and the occasional fireball!!

Microwavable grape plasma - Grape plasma in microwave experiment
What happens when you put a grape in a microwave?
Find out by watching this video!
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.

Microwave This: Grapes
Experiment #036: Grapes
~~ Is It A Good Idea To Microwave This? (Quickies) ~~
A comedy/stunt/science hosted by microwave specialist Jory Caron, and his team, who microwave different objects... so you don't have to! The Jory Caron Microwave Laboratory is an experimentation facility equipped with tinfoil shielding, industrial fans, emergency surge protectors, safety masks, and many sexy microwaves. Now partially retired, the show originally ran from 2007 to 2011 (on the Jogwheel channel), satisfying YouTube's curiosity with dangerous and amusing experiments twice a week. Now, this Archive channel is home to remastered, and re-edited streamlined versions of all 300+ experiments performed on the show.

Putting a grape in the microwave is really cool (makes plasma)

Grape in Microwave Making Plasma
Here I do the trick of slicing a grape in half and microwaving them, making plasma where the slices touch. If you decide to do this yourself then make sure you have VERY GOOD VENTILATION since the smoke from this is not good for you. Also you can prop up a glass above the grape and it will make a ball of plasma in the glass.
