(music plays)

In animation, the name of a craft show appears against splotches of colourful paint. It reads "Create."

A caption reads "Marbling: How to marble rocks."

The caption changes to "You will need."

The list of materials for the craft reads "A bowl, a small container, water, nail polish, paint and a brush, rocks, container or bowl."

The steps for the craft appear on screen as the instructor goes through them.

They read "Paint the rock white. Wait for the rock to dry. Fill both containers with water. Flick nail polish into water. Roll the rock through the water. Drop the rock into cold clean water to set. Wait for the rock to dry."

The instructor places three decorative rocks in a plant pot.
