Mark Rober has introduced a "$100 Slime Challenge" in a new video promoting the CrunchLabs Slime Prank Lab [1].

The initiative blends educational entertainment with product promotion, targeting a young audience interested in science and engineering through hands-on experimentation.

Rober used the video to showcase the capabilities of the Slime Prank Lab, a kit designed for creating various slime textures and effects. The challenge specifically involves $100 [1], though the video focuses heavily on the creative application of the materials provided in the kit.

The product is now available for purchase through several major retail channels. Customers can find the CrunchLabs Slime Prank Lab at Walmart, Target, and Amazon [1].

Rober has built a reputation for using high-production videos to explain complex scientific concepts to millions of viewers. This latest project continues his trend of integrating commercial products with interactive challenges to engage students and hobbyists in STEM activities.

This move signals a continued expansion of Rober's CrunchLabs brand into mainstream retail. By leveraging high-engagement challenges to drive sales at big-box retailers like Walmart and Target, Rober is transitioning from a content creator to a scalable educational product developer.
