We often see things in the world around us rapidly changing.For example the flutter of a butterfly’s wings, or the flicker of a poorly functioning lightbulb.This task explores the speed at which you can make objects flicker in your mind’s eye.

Think of all the things that spin and twirl around us. Cricket balls, rollercoasters, spinning dancers, ceiling fans, wheels and so on. In this task, we are going to ask you to imagine rotating things as fast as possible.

We often imagine, and practice movements in our heads. We picture how we would look performing a dance move or choreograph steps inside our imagination. Similarly, we can also re-imagine a dance performance.

Just like dance, we can also imagine our workout sessions and exercise routines. This task is similar to the dance task you just completed.

Here, we put another feature of your imagination to test. How long can you continue to imagine something before it breaks.

Once again, we will test how long you can continue to imagine something before it breaks.
