Toy puts something big through a doughnut

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Toy decides that the biggest thing he can think of is his voice. He gets close to the doughnut hole and sings a long, loud, operatic note. He briefly considers finding something physical to pass through the doughnut, but decides it’s not worth the effort or risk. He tells Nuno to (somehow) convert decibels to centimetres, and leaves. Toy’s voice is measured at 95 decibels. Vasco accepts the conversion of 1db = 1cm, and Toy wins the task.
