Interesting. I've said nothing about geysers...
You are one of the only supporters of Cladking's Geyser Theory.
If you disagree with the above statement, just say so.
I've seen a few cite Houdin as a possible explanation, but I actually haven't seen much promoting of any Cecil B. DeMille ramps in recent years. It may have been silently put to pasture. Long live ramps. Either way, step or core tower, your cold water geyser can apply.
