If you're going to play around with explosives, an old knowledgeable teacher is best. I imagine incompetence gets weeded out early. The guy in the video has been in quite a few others too. It's fun to see how the hosts are usually a little nervous and he's calm as can be.

And he still has 10 fingers! Unlike, for example, Mark Pauline ( https://en.wikipedia.org/wiki/Mark_Pauline )

> much like a jet of hot water melts through a block of ice cold water can cut through steel also... https://www.youtube.com/watch?v=v0NVOThRooE
Waterjet cutting uses water to propel a powder which acts as an abrasive, like an infinite stream of sandpaper. I don't think water by itself will achieve much.

It's all fun and games until you realize your country has no deniability about being at war with Russia.
I think the line is when your troops shoot their troops. Providing weapons has been a US-Soviet past time for the whole Cold War. In this case, I think the US could have even moved in troops without being at war, early in the invasion. It just needs a pretext. By far the best response a week in, when Russia claimed chemical weapons, Nazis, etc., would have been to send in a multilateral force to investigate Russia's…
I've got a feeling we might be pulling a Russia... Ie. None of our troops are there officially, bit there's an awful lot of troops volunteering and 'on holiday' and 'advising' there.

The younger guy in this clip actually ended up retiring because he got brain damage in a contraption he designed for this show. https://www.bbc.com/news/uk-58762935

The explosive is stable (small cubes of most plastic explosive can even be lit on fire and act as fuel). But there is still danger in correctly handling/connecting the detonator. I'm not sure, but I thing the acceleration charge might be a less stable type as well (obviously they aren't going to give us step by step instructions).
> (obviously they aren't going to give us step by step instructions). nitrocellulose is very simple to make and detonate... and is also very stable.... I don't see why we need secrets... I played with that stuff when I was a teenager

"What makes me a good Demoman? Well if I were a bad Demoman, I wouldn't be sitting here discussing it with you, now would I?" One of the silliest, hilarious but on point thing I've ever heard uttered from a video game character
Not problems like 'What is beauty?' Because that would fall without the purview of your condundrums of philosophy.

Count the fingers. More than 8 is probably OK. age may be a drawback, one gets too old to meddle with some of the more fun things eventually.

Great find @ 0:40. The only thing it doesn't convey very well is the older man's explanation of the copper spear curling outward on itself. From the simulation, it seems like it is just punching through and maintaining its rigidity somehow.
iirc, nothing is rigid, it's just very high energy jets, so they don't deform much. like particles in water jets cutting steel.
