Ishihara test is now my new E.D.C.
The colourblind test is so extremely easy to perform.
Also the reset is practically instant.
Everyone wants to see if they are colourblind or not.
So it's an instant hook for all the spectators.
With a fabulous ending which no one see's
coming.
This is one of my favourite tricks to perform.
I'm a 83 O.A.P. & will not go out
without this packet trick.
An O.A.P. I'll assume that interprets to Old Ass Person, eh? That's great, I'll have to start using that because I'm also an OAP at 75. And you're right. This is the perfect trick to always have with you. Enjoy!
