Jody was working near the acid vats one day when she noticed some aluminum on the floor that was quite corroded from some of the acid that had spilled on it. She then made his way to the top of the vat to inspect some equipment. There was a tour and the group just happened to be coming by the vats just then. The guide pointed to the warning signs on the vats that read "caution: corrosive" and went to move on, but as luck would have it Jody recognized someone in the group and leaning over the railing to wave, slipped and plunged into the vat.
The crowd gasped sure that the Jody would be instantly dissolved by the acid. Another worker rushed over and pulled her out. Jody yelled down "I'm ok".
The guide remarked that wasn't part of the tour and asked people to move on.
If Jody wasn't wearing any protective clothing or had any special protection form the acid, how did she survive.
I expect this to be solved almost immediately, guys.
