Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.

Why Wisc-Online Moved to WisTech Open

In January 2026, Wisc-Online transitioned to WisTech Open to better align with current educational standards and long-term goals. During this process, the catalog was reviewed and content that did not meet accessibility requirements or was outdated was removed. Games were also taken down, and the team is evaluating the possibility of adding them back in the future with accessibility and quality standards in mind.
