why do mirrors flip you side to side and not upside down that's very good yes yes
why is it two eyes two it must be your eyes are level okay let us imagine that we're looking at
writing on a t-shirt yeah and you can read it perfectly well and then you look in the mirror the
writing on the t-shirt appears to be flipped that way like that so you can see it back to france
yeah why is that why does the mirror do that and why does it not flip us upside down as well why
does it only flip as apparently left to right is it not what alan said about your eyes being
left and right i like your eyes on the side of your head when you do that yeah
like a fish is your eye seeing actually what it is does your brain does your brain flip it have
you had a stroke yeah when it comes in your eye it's already flipped right and your brain flips it
around what he said what he said i think everybody is making it much too complicated so here's what
we're going to do we're going to try this and joe is going to be my assistant joe i want you to take
a piece of card that we have got here yes write a large clear word in capital letters
oh my god are you going to try and guess it no i don't want to guess it it's not a magical trick
what's the point then i want a magic trick okay lisa could you start the word any word anywhere
darling what about the word boss for example which you know lots of people have a boss
okay looks like we're off to court
right and can you write the same word on this piece of glass okay so i am going to go over
here and uh stand in front of the camera and the glass and you can see hopefully
are the audience able to see this can you see it on the monitors everybody so you can see
uh that it says boss now when i have it as it were on my t-shirt and i look in the mirror it is
it's flipped around okay yeah so the question is why does it do that
well the mirror hasn't done anything it was me who flipped it route there is absolutely nothing
happening in the mirror if you look at the card i am flipping it around and the mirror has not done
anything and in fact if you bring the glass darling bring the piece of glass over here
uh have you written the same word on the piece of glass yeah okay so come here my darling
let's put the card behind it let us imagine there it is can you see that perfectly well uh there
it says boss um but if i don't flip it around now because it's written on glass when we look
in the mirror it is perfectly fine the mirror has not done anything it is me who did the
flipping around um thank you my darling the most brilliant magician's assistant there
try and imagine if you were a fish and you had your eyes on either side of your head and
the fish we've got a picture of a fish swimming there we go so a fish swimming alongside a mirror
would see the eye exactly where it's supposed to be and the tail exactly where it's supposed to be
it it would know that the mirror has done nothing the flipping is done by us and not by the mirror i
don't think i've ever questioned that no and then actually once you do start thinking about it it
does slightly do your heading so hang on is alan over there because i've done it in my head yes
everyone's done me in their etcher
you know what i haven't but i am now whoa is there a mirror thank you for
