When you surround something with smaller things, it looks bigger!
On their second mission, Sally and Nick examine two orange dots and discover that one appeared larger than the other only because one was surrounded by larger circles, and the other was surrounded by smaller circles. When they held the two orange dots together, they observed they are the same size.

For this fun fact finding task, you each have to look at the two orange dots in the center and tell me which one is bigger and which one is smaller.
This looks too easy, Cat.
Yeah.
The orange dot in this one is definitely bigger.
Right, and this one is smaller.
So, you both agree that this dot is bigger?
Yes, but just to prove it, let's measure.
Bring that dot over here, Nick.
Huh?
They're the same size.
That's impossible.
I knew there was a catch.
But what was it?
There's something different about these two pictures.
The grey dots in this picture are all big.
And the grey dots in this picture are all small.
So, maybe the small dots in this picture make the orange dot look bigger.
And the big dots in this picture make the orange dot look smaller.
Another fun fact you were able to find!
And now that you know, have you both changed your mind?
(Laughing) Yes.
I have.
