Visual illusions are fun. They boggle the mind and tickle our fancies.

2
00:00:10.500 --> 00:00:15.500
They can delight us and often surprise us.

3
00:00:15.500 --> 00:00:22.000
But they ask a serious question. Do we see the world as it is?

4
00:00:22.000 --> 00:00:30.000
This question is important because we so implicitly trust our senses

5
00:00:30.000 --> 00:00:35.000
to guide us around and help us interact with the world.

6
00:00:35.000 --> 00:00:41.200
In this activity you will try your hand at several visual illusions

7
00:00:41.200 --> 00:00:48.000
