"science does not work on opinions but instead only facts..." Couldn't agree more. For instance, geysers are episodic - your model (essentially just boiling water that entrains liquid out of a funnel) isn't. You mention three place most geysers are... missing the 2nd largest (Kamchatka) field on Earth. There are some great papers, freely available, on this. For instance: "Geyser model with real-time data collection", by Samo Lasic and Gorazd Planinsic (Google it; the PDF is on-line)
You have a right to your opinion on how geysers work but opinions are like lil drugs that make us all feel better. Opinions are not facts, and science does not work on opinions but instead only facts. You have the right to challenge my explanation if you want but I highly suggest you dont. If you check any encyclopedia (NOT WIKIPEDIA THEY ARE NOT AN ENCYCLOPEDIA BUT A CHURCH WITH OPINIONS) you find that the description that I have given is a scientifically accurate description on geysers.
Um... Fun presentation, but not really the best description of how a geyser works... or how to build a model (I've been building models for a while, take a look at my channel for both animations and a number of models erupting).
