choice tidbits

First assignment in freshman chem lab: read the appendices (safety, procedures, etc.) and fill out a short worksheet. A couple of choice responses I got from grading:

What should you do in case of a chemical spill or accident?
Call the TA and do whatever she tells me to do.
And what would you do your TA got knocked unconscious during the accident?

What is litmus paper?
A biochemical assembly with a molecular weight of about 3300.
Correct to some extent, but why should I care what its molecular weight is?
