Learn English – What does “MM” mean in this context

Experimentation is the act of doing experiments.

So you would say "I am conducting new experiments at the laboratory"

eg. "not all experimentation is done in a laboratory" means sometimes experiments are done outside the lab.

The second example is not rude in the slightest. It is a like saying "would you be so kind as to...." and is in fact a polite way to ask somebody to do something, implying that there is no requirement for them to do it but that it would be kind if they would do it anyway.

The first example is not technically correct in English, unless you mean to imply that it is kind of you to ask the person to do something, but it is very commonly used and is understood as a gentle way of asking someone to do something, very similar to the second example.
