Pretty much; volcanos have some of the same "degassing" processes driving them (along with reduced pressure induced melting).

No worries! It works, and if you are familiar with the origin of it as a LEGO version of Digicomp II it makes a lot of sense. The video wasn't really there to explain it in detail, just show the principle of operation

Yeah... it's old, but still fun.

Yes, actually. Beehive geyser in Yellowstone has two clearly related outlets, and many geysers have multiple outlets. So it's not an unusual situation, and I wanted to show ONE way both could function.

Generally, it's due to an input of very hot steam from much deeper in the system. This heats up the water. Note that often the entire ground around and under these is already very hot.

How well did it age?

@@brdavis5 I'm not sure that videos do age. Sure it's a snapshot of a different time and a different level of technology, Lego's NXT era filmed with a lower-quality camera, but the video is the same as it always was: some friends getting together to add some dubious modifications to lego bulldozers and make them fight. It's fun and funny and makes me want to build a Lego, same as it did back when I was a child. Videos like this really inspired me back when I first got my first Mindstorms and power functions, and that's what started my channel. Hasn't seen much activity recently, but I've never outgrown this.

Concord high school in Elkhart indiana.

Nope we’re in Elkhart indiana 🤣

@@stantwice786 oh lol the concord high school in California has the same mascot lol

In a similar fashion actually - in a 'cold water geyser', it's dissolved gases that are kept in solution due to the increased pressure, instead of water kept in a liquid due to increased pressure. But both work similarly, in that a release of pressure drives the gas in to bubbles which reduce the pressure further, leading to a runaway.

Some systems don't reach a steady equilibrium - think of things like predator/prey cycles. It's a balance between water inflow and heat inflow... too much heat, and you have a steady boiling spring. Too much water, and you have a steady warm artesian spring. But somewhere in the middle (with a certain plumbing system), there is a third possibility which is stable cyclic eruptions.

Generally, yes - silica is dissolved from rocks deeper and at higher temperatures, and than precipitates out nearer the surface.

Yep. You use what works ;)

I guess... because that many people, over the years, have subscribed to me :). Not just for this video (my LEGO videos actually got a lot more hits).

Oddly... I do. And, I did 7 years ago, too. All these USED to be nicely sorted under their questions. Sigh... thank you YT for breaking some other legacy stuff somewhere.

@@brdavis5 That’s funny

Well, that certainly is an interesting viewpoint. One that has little to nothing to do with the subject of the video, but perhaps that wasn't your goal.
