I have no idea what direct, curricular material science connection this would have, but it's worth sharing.
I have so many questions that aren't answered by the video's concise description: "A tapper opening a taphole in the side of an iron furnace. Using an oxygen lance."
- Why wasn't there already a hole?
- How much did that dude have to get paid to do this?
- Is this a regular occurrence, or did something go wrong to require this action?
- What sort of safety equipment would have to be involved - because it doesn't look like nearly enough?
- Is this a field trip we can take from one of the summer teachers camps?
- Are either of those 'sentences' in the description really sentences at all? (Don't worry, I already know they aren't.)
