Rice Cooker, Yellow Culture, and Cold Glycerol

Today I Learned:
1) Our lab has a rice cooker in the lounge. Mid-day steamed buns may have to become a thing.

2) E. coli cell extract turns vibrant yellow when bleached! I'm guessing it's not the actual cell innards that turn color, though, because actual E. coli turns colorless when bleached. It must be one of our buffers.

3) When glycerol is drizzled into liquid nitrogen, it tends to bubble and foam up a bit before crystallizing. If it forms small bubbles, it will harden into a solid foam with a similar appearance to cheetos or styrofoam. It can also form large, singular bubbles, it harden into beautiful, delicate shells.
