Watched as if hypnotized and then it was over. I even thought for a few seconds I might be able to make this.

That was very coolā¦ and yes, it looks pretty simple. I should try itā¦what could possibly go wrong???

I was so relieved when he finally used vice grips to hold something he was drilling or cuttingā¦ Once 
But that is very cool, All I really need is a soda can and bearings, Iām sure I have some (what looks like) 5mm aluminium plate.
Now what could I attach it to

Yeah, I winced a bit with that utility blade, slicing that can. A friend 
of mine might have done something similar recently when he was too lazy to go get his glasses.

When I see something as advanced as a jet engine being made with such simple items I wonder how much history could be changed by sending one to the past, letās say early 1900s. 
Of course this specific Jet-in-a-can or āI canāt believ itās not a jetā couldnāt be used as it is, but it would give the scientists of the time something to toy with.
Itās the idea behind it- a hundred years of technology condensed in a simple experiment.
Darn. So cool.
PS: Yea I winced too at the bit of careless tooling

They had the ideas, but I think they were held back a bit by the materialsā¦

They knew the tech for a long time, it just took a lot of effort to optimize it to the point where the people in power could be convinced it was worth it.
As late as 1939, experts at an aviation conference concluded that jet engines were ātoo heavy to ever be used in airplanesā.
Just like people who now say that āwe will always keep eating (some) meat/cheese from real animalsā

Or I could be wrong and Iāll look like the people who thought everyone would have:
- tabletop nuclear powerplants
- 3D televisions
- ā¦?
Time will tell.
My point is, the obstacle for innovation is usually more peopleās beliefs, existing power dynamics and limited evidence / optimization / resources than the core idea itself.

You need to request a cat on an emergency basis to knock some things off tables to check that gravity is working correctly down thereā¦

I have been awake since 5am due to a kitty walking across a āfull bladderā. Gravity is definitely workingā¦ But I think you might be onto something, it is stronger than usual because I swear that cat weighed about 20kg

So, thrust you can trust to not rust, but it might turn your house into dust!

I do wonder about the wooden parts that were includedā¦ Seems almost inevitable that they would eventually burn to a crisp and be a fire hazard, so why not make it all of metal, or at least of something less flammable?
The wooden stators operate in air at or slightly above room temp due to compression. Since the compression on that engine is very low (tolerances, number of compressor stages, lack of duct area reduction, etc), the burner inlet temperature is also very low.
