Not looking forward to tomorrow......2 IB classes have just finished setting up the egg white & pepsin prac....because of the replicates they do, they've filled all the waterbaths with 180 test tubes......that's 180 eggy farty stoppered tubes at 40 degrees....that they'll be opening tomorrow.
Sorry, just feeling a bit 'poor me' considering the aftermath & washing up to come
The egg white came out a treat though, I lined an old steel surgical tray with gladwrap & steamed it in a waterbath at 90 degrees, so I ended up with a big solid 'loaf' of whites to slice & cube. Pity the prac reeks so badly though, it's actually a good one to demonstrate enzymes.
After the first class set up (& with the very strong stench wafting in from the prep where I sliced the egg) the second class came in almost gagging. Some of the girls look a little green, & I heard one of them say "I'm NEVER eating eggs again!" in a very dramatic voice.
