I have a new favorite game. 

Aide, another postdoc in our lab, is working with tiny box jellyfish called Tripedelia. We have tiny baby polyps growing in the lab, and last week, we spotted our very first medusae. But the medusae have to live in a special tank, with waterflow angled to keep them from getting stuck in a corner. So we get to move them.

You roll up your sleeves, you grab a plastic Pasteur pipet, and you stand over the polyp tank until you see a medusa float by. And then you suck it up and run it across the room to the other tank. You gently release the jelly into the tank, and watch long enough to see him pulse his bell to swim away from you. Repeat. 

It's meditative. It's hypnotic. It's ridiculously fun. I'm not alone in this opinion; let's just say multiple people a day are moving medausae now ... just in case... wouldn't want to miss one...
