Hi, everyone. My name’s Tim and this is the taste test.
What we’re going to do is we’re going to see just how well people’s sense of
taste goes when their sense of sight and sense of smell is taken away.
So what we have down here is some different flavoured juices.
To start with, we have orange juice.
Over here we have pineapple and orange juice and
finally we have pineapple and passionfruit juice.
What we’re going to do now is, I’m going to disguise
them by putting in some red food colouring.
I’m going to start over here and put some red food
colouring in there and give it a nice stir around,
disguise that colour and do the same thing over here,
give it a stir around
and finally finish off over here.
So now that they have changed colours we’re going
to lose the cartons, and what we’re going to do is, I’m going to call
someone over and we’re going to see how well their sense of taste goes.
Rachel can you come over here.
Now Rachel I want you to try these different
drinks here and tell me which flavour is which.
Can you try this one?
What flavour’s that?
That’s definitely orange juice, Tim.
Very well done Rachel.
So that’s the first one. How about the second one?
Well I can smell pineapple so I thinks it’s pineapple and orange juice
Pineapple and orange very well done. How about lucky last this one here?
Well that tastes like pineapple too but with an undertone of passionfruit
Very well done. Thank you, Rachel. You can step off now.
That was pretty easy. Let’s see if we can do it with someone who doesn’t
have their sense of smell and someone who’s been in the cone of silence.
David can you come across.
You don’t look too well.
I think I’ve had a bit of a cold. I can’t smell anything.
OK, can you try this one here.
Oh alright.
Is it tomato juice?
Nice try, David. Let’s try again. Maybe you’ll get this one.
Alright ah
tomato soup, is that it?
No, no. How about third time lucky. Try really hard this time, David.
I think I got this one.
Yes, yes,
it’s bath water isn’t it, Tim? It’s bath water.
Ah no, thank you, David.
If you want to find out why David wasn’t able to taste those
drinks then head to the Questacon Science Squad Website.
Catch you next time.
