Last night, my son was inside my water truck welding a spot of damage. I was manning the ventilation equipment and making sure he was alive through the process. I could watch his progress by looking up from below watching the orange glow of the steel. In one spot he burned through. A glop of molten steel dropped, bounced and went right into the back of my mouth. I instinctively swallowed.
So, I can say I have swallowed molten steel. (sore throat this morning). Stay thirsty my friends.
