Your calculation only tells how much energy is needed to heat the water to 100degC, not how much is needed to boil it (convert to steam).

If you created negatively charged forcefield around the lightsaber then you could do the same with a positively charged lightsaber forcefield and they would repel depending on how strong the fields are meaning you could clash them together

This thing won't work in a vacuum. The gas expansion into vacuum will immediately spread out the fuel and oxidizer gases when they leave the nozzle and it would be pretty amazing if you can even maintain combustion or provide enough gas to offset the vacuum pump.

Also note that the biggest reason that it worked is that the conductivity of air is very low. If you instead touched a copper piece of metal that is hot it could transfer that heat much much faster to skin, causing at least some warmth or damage pretty much no matter how short of a time you were touching it. It's the reason why you could put your hand in a 400 °F oven for quite a sustained period of time without any problem, but if you touched a frying pan (particularly aluminium) at that same temperature (or even lower) you'd instantly get burned.

I wonder... If he slapped the nozzle fast enough from above... Could the wind have put off the flame? Causing the blade to shut off? He has the force! The force to shut off an opponent's lightsaber with his bare hand!

I'm kinda upset that he didn't even explain the leidenfrost effect. That is also a huge part of why his hand doesn't heat up as the beam wraps around his fingers. To anyone reading this, the effect works much the same as a bead of water on a hot pan. The temperature difference is so great that a thin layer of gas separates the beam from his hand, causing it not to heat up instantly. That's why he didn't feel anything when he put his hand in. This effect works in tangent with heat transfer, so what he said is not wrong but it's also not the full truth. either way, its still a great video and I can't wait to see what you do next.

just something thing about kybur crystals they can exurb a lot of energy and disperse it normally leading to a very powerful explosion Jedi use a focusing crystal to focus that energy that power into a focused beam that goes up and then down witch is where you get the vibrating sound cuz the blade is spinning
