Here's the email which accompanied the picture...
Dr. Poliakoff and Team,
We wanted to share a photo of our son, Joshua, who decided to dress up as Dr. Poliakoff for Halloween this year.
Joshua loves The Periodic Table of Videos that you all produce.
He is 8-years-old and has a special interest in the elements, chemistry, and physics.
Thank you for all you do – there is a little boy in Blythewood, SC (USA) who appreciates it!
Dana and Max (Blythewood, SC)
Joshua is not the first person to be inspired by The Prof for fancy dress purposes - here's me a few years ago!
