Stephen and his sister Grace compete in the "Twin Telepathy Slime Challenge." The challenge consists of five rounds where they have to choose the same slime ingredients without seeing each other's choices. The ingredients include glue, glitter, food coloring, accessories, and more glitter. Stephen takes the lead with three points, but a surprise sixth round introduces a new ingredient, and the winner is determined by the audience's votes on who made the better slime.

The challenge is part of a series, and the winner gets closer to winning the overall grand prize of $10,000.
