The specimen is thawed and we now have to add formalin to preserve it – as formalin is toxic the scientists have to wear full protective gear while pumping 600 litres into the tank. The smaller specimen is being preserved by injecting 3% formalin into the tissue. Once the formalin has been pumped into the tank, we will replace the lid and head off home for a good night’s sleep. For those of you still watching I understand that some recorded footage from today will be screening for a while this evening.
The plastic lid will be put over the tank, then the wooden lid. Steve O’Shea and Mark Fenwick will be here all night monitoring the pH at 3 hourly intervals – and adding bicarbonate to keep it as neutral as possible so that the hooks and beak don’t dissolve.
Cheers. Thanks for watching
