i thought it would extinguish

Watched this 11 times, my brain hurts.

this is above my pay grade

That's why it doesn't take much electricity to open a wormhole,
Your really Kool

I mourn the demise of the pneumatic trough, beehive shelf and gas jar. RIP.

ILL GO ON TO THE NEXT VIDEO

Actually, it's more like hot and expanded air from the candles replaces the air in the tube, and when the candle is off, it cools.

,,, you create an area of high pressure 😉

Can you explain how air cools down instantaneously??

Wrong negative pressure inside from extinguished candles PULLS the water inside

I'm so glad I know that now. What can it be used for?

Some people have too much time on their hands.

What a mess and waste of candles.

When was there time for the air to cool? Since air is 21% oxygen it accounts for most of the water volume going into the vase, so guy was wrong.

good physic teacher

Isso só acontece por que elas foram cobertas por um recipiente, no vácuo seria impossível

He's basically made a thermometer

Bullshit same thing happens with candle in milk bottle and boiled egg . The egg is sucked into the bottle with no “cooling” water . Please explain again about oxygen loss not causing the vacuum

And in an alternative universe the cooling atmosphere draws the water into the vahse

The number of gas molecules per unit volume is constant at fixed temperature, pressure and volume – Avogadro's Law. When the vase goes over the flame, the temperature inside goes up. The causes the gas molecules inside the vase to flow out as the gas inside expand. Thus there is fewer molecules per unit volume inside the vase. Once covered, the molecules inside the vase cannot escape. This causes the pressure inside to rise as the air inside warms further but this ends quickly because the flame consumes the oxygen inside quickly. The air inside cools back and thus contracts causing the water level inside the vase to rise.

It's differential air density

There's too much arguing going on in the comments, so – To prove whatever is the cause, let the water cool, then raise the jar slightly. If the water level drops to the original level, the heating is responsible. Otherwise oxygen depletion is.
Talk is cheap. Proof is Science. So get up off your arses and do the bloody experiment.

False

Try with fine steel wool instead of candles. The consumption of oxygen from air is by far the most significant factor.

Try it with a mouse instead of a candle.

Yeah, and tree leaves create the wind. Thermal expansion of air is less than 4% for 1000 degree change. Consumption of the oxygen by flame would change the volume of gas inside by nearly 20%.

You know that was the last thing I was thinking?

Well warm air has less density so volume increase and pressure drops so to full fill that vacancy water come in play

上升的高度，就是室內含氧量…..

THAT IS NOT WATER MATE… I WON'T SAY WHAT IT IS, SO I WON'T BLOW YOUR EXPERIEMENT DUDE 😅😅😅

What a terrible explanation

Thank you for the science.

Yea but we used to light joints like that 😂
