On: Here's what happens when you throw a bottle of water into a vat of molten steel

I tried to find the original video, in e it has more information. The oldest I could find is: https://www.youtube.com/watch?v=78CBUcGtfOs

Do anyone know what EAF Tappi / EAF Pulpi means? Can anyone translate the initial message in Arabic?

Electric Arc Furnace Tapping and my guess for "Pulpi" would be "Pulpit" (as in: Control Room Pulpit Operator).
