October Project Puns

On October 23 (6.02x10^23) in my chem class we celebrate mole day. You have to make a project revolving around a mole pun. This year I did MoleDemort and printed a life size Voldemort with a mole head, but I'm out of ideas for Chem 2 AP next year. Want to get ideas early on, any suggestions? Some examples already taken that I don't want to repeat: Darth Mole Moleverine

I will add more as I remember, or if you come up with one that's already done.

Thanks in advance.
