Observation test: five cards, the backs and a T-shirt

Jamie posted this to-camera clip with the caption "Observation test". He stands against a plain wall and talks the viewer through a short test.

He starts in a grey T-shirt with five red-backed cards (frames 0:00 to 0:02). At 0:03 a close-up of the red backs carries the text "REMEMBER: 5 CARDS! AND REMEMBER THE BACKS!" When the camera comes back at 0:05, his T-shirt is blue.

He then works through the cards one at a time. At 0:18 and 0:19 he holds up an ace while the caption says "SPADES". At 0:26 to 0:28 he fans the cards again, and the backs are now blue. At 0:29 the caption reads "MISSED". At 0:30 he shows a flush in spades.

At 0:33 to 0:35 he points at his chest as the captions read "T-SHIRT", "COLOUR" and "WATCH". The clip then plays a second time from 0:36. It ends on a card with "JAMIE SKELTON MAGICIAN & MC" and www.jamieskelton.ie (1:14 to 1:16).
