Countless observations of bumping have been recorded.
You can buy stuff to stop it.

If you can't replicate it, that's your screw up.

Nevertheless, my setup can still consistently produced superheated water when microwave oven is used. Which was the reason why I tried to identify the difference in the first place.

Infrared thermometer has its own challenges, since it's affected by emmissivity of the surface.

I have good news for you.
The emissivity of water near its boiling point is the same as the emissivity of water near its boiling point.
A more interesting problem is how far into the water does the thermometer "see"?

What about at the center?

What's the highest temperature of superheated water have you ever measured?

Just like any hypothesis, its veracity still needs to be verified.

What experiment would show it to be false?
Come back when you have tested it.

Microwave ovens used to heat food are not set to the frequency for optimal absorption by water. If they were, then the piece of food or liquid in question would absorb all microwave radiation in its outer layer, leading to a cool, unheated centre and a superheated surface. [4] Instead, the frequency selected allows energy to penetrate deeper into the heated food. The frequency of a household microwave oven is 2.45 GHz, while the frequency for optimal absorbency by water is around 10 GHz.

Here's some info to consider in experiments using microwave oven.

If the container can be heated from the outside to be hotter than the water, and the water is still superheated.

I just finished editing my old video using microwave oven to heat up a neon test lamp. It breaks down and burn in flame, and leaving some smoke. Instead of explanations, this short video asks some questions, like which part of the neon lamp absorbs microwave energy the most? What's the nature of the flame and smoke?

This video explore the danger from microwave oven for those who are curious, while still want to enjoy the safety behind a monitor.

I Tested the Limits of a Microwave

I'm still surprised how the experiments went at the end

Please note: This is for educational purposes, I don't encourage people to try this themselves

Neon lamp can take various shapes.

Try searching for neon lamp tester.




Try searching for fuse type neon lamp.

In this video I demonstrated how microwaves lose a great deal of their power, when you step away from the antenna source, In case you're wondering how far away I can get from my Lectenna, and light them up with my microwave, it was 37 feet.

How light can vaporize water without the need for heat
Surprising ?photomolecular effect? discovered by MIT researchers could affect calculations of climate change and may lead to improved desalination and drying processes.
David L. Chandler | MIT News
Publication Date:April 23, 2024

It?s the most fundamental of processes ? the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation is all around us, and humans have been observing it and making use of it for as long as we have existed.

And yet, it turns out, we?ve been missing a major part of the picture all along.

Perhaps there is also the inverse effect of this "photomolecular effect?, where water doesn't evaporate even when it has received more energy than required to boil it.

New MIT Discovery Just Solved Water's BIGGEST Mystery!

Scientific discoveries have a way of changing the world. Like the photo-electric effect that paved the way for LEDs and Solar panels. For a long time, we thought the sun evaporated water by heating it, but a new discovery on the Photo-Molecular Effect might just change our understanding of the water cycle forever. And there just might be countless new innovations that stem from it. From more efficient desalination, to new methods of keeping cool, this has the potential to be a gamechanger! So how does it work, and just how impactful might it be? Let's figure this out together!

Microwave Oven Standing Wave Visualization

This is an experiment that I devised to help visualize where the hot spots are inside of a microwave oven. I came across some thermal paper yesterday and decided to put it to use.

The microwaves inside of a microwave oven are electromagnetic waves and are reflected inside the oven. These waves interact with each other and form interference patterns that result in areas that are intense and areas that have essentially zero microwave energy. The thermal paper forms a thermograph of the interference pattern.

I performed the experiment three times, once with the thermal paper at the bottom of the oven, once with it two inches above the bottom, and once with it on the carousel.

We are lucky that someone is willing to take the risks to find out curious things about microwave so we don't have to.
There are many interesting experiments in this video, but the water boiling starts at around 6:34 to 7:00.

Spoiler: show

The water seems to explode, or at least boils quickly at the upper part of the glass. Unfortunately it doesn't show indication of superheating, which can be done by disturbing or contaminating the seemingly calm water after being heated by microwave. He didn't mention if he used demineralized water.
