Thought the periodic table clue was almost impossible to get. The rest fine

Really enjoyed this - did NOT get the periodic table clue though :)

I got them all and I'm a bit embarrassed about it.

My answer was that they all started with an elemental symbol. It was almost a throwaway guess because that's a really broad category.

So, not really sure I deserved that point!

Really great wall though.

Penn needs to be his surname surely

Queen-of-Corona, you're probably right :-) But it helped with my Dynamo red herring!

Dysgwr - VCM would have given the point if it was an early round, but semi on onwards, I think more info required. Good going though!

Very interesting and diverse Grid. Fairly easy to solve except for the periodic table which completely defeated me. Very impressed by those who recognised Dy and Re as chemical elements
