Parafilm "M" (M's a mystery...) and its many lab uses

Parafilm is like a heavy-duty, super-stretchy, water-repelling, saran wrap. We use it in the lab for lots of things including:
- wrapping petri dishes
- preparing agarose gel samples
- covering beakers to prevent evaporation
- covering graduated cylinders to mix solutions by inverting
- sealing bottles of hygroscopic (water-absorbing) solutions

It's super duper duper awesome. Just take a small piece, hold one end down and gently stretch around the thing and stick it back on itself. Voila! You've got a seal! See the appeal?
