Mawaan uses the washing machine

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Mawaan taped a tea towel around the marble and put it in the washing machine for 1 hour. However, his fellow contestants argued that Mawaan affected the marble's movement after releasing it by pushing the button on the washing machine to make it work. As he result, Greg disqualified him from the task.
