    Wet specimens

    My top tip would be don't do it. We had loads of incorrectly sealed specimens here when I started, random bits of roadkill and other items that a previous teacher thought were wonderful. I don't want to breath in the fumes of these no matter how minimal, and I'm sure the students of whichever...

    Hyacinth bulbs

    I had some hyacinths growing in bulb forcing vases and forgot all about them until alerted by the smell. If I just leave them to dry back will they be any good for next year if I refrigerate them? Thanks

    Does anyone, use Cobalt blue glass, for viewing Mg burning/flame tests ?

    Welding filters for thermite and magnesium. We have blue glass for flame testing but it's rarely asked for.

    Using baby powder in a lab

    They are only meant to use a small amount to sprinkle over the beam so it shouldn't cause that much of a problem.

    Surplus Glassware

    I've tried getting rid of bits on here, ebay and facebook marketplace but never had any luck. Did end up donating a fair bit to the art department for drawing though.

    Exam invigilation

    If it stops them bringing in external staff then maybe it's a good thing. It makes sense for the school to limit contact with outsiders. Right now a lot of staff are being laid off, hours reduced etc and if there was ever a time to 'play ball' I think this is it. All be it a tad extreme the...

    Exam invigilation

    How busy are you with practical requests or have your school stopped doing them? What I mean is can you justify saying 'no' without looking like an unhelpful eejit.
