After a long weekend of waiting we were once again greeted by disappointment, there wasn't even a hint of glowing from any of the agar plates. They haven't survived the weekend for whatever reason, it is most probably the time scale rather than the lack of nutrients on the agar plate as we have provided everything they should need.
So it was off to the arndale centre again to purchase another squid, although this time we got two for no other reason than the minimum card payment was a fiver and we had no change. We took them back to the lab and went through the same procedure as before, covering them in salt water and putting them in the dark in a shoebox, however this time we put the box into the fume cupboard to aid with the smell! At least they have a friend now and might be a little happier together.
