Gels

“

We haven't entirely nailed down what element it is yet, but I'll tell you this: it's a lively one, and it does NOT like the human skeleton. Click to listen — Cave Johnson

Gels are a gameplay implement introduced in Portal 2. They are paint-like liquids that impart different effects on surfaces and objects.

Gels

Repulsion Gel

Repulsion Gel is a light blue substance that repels objects. A player or an object that hits a surface coated with it bounces off. Jumping off such a surface launches the player higher than a normal jump. Objects such as Storage Cubes and Turrets can be covered in Repulsion Gel, which causes them to bounce around erratically.

Propulsion Gel

A bright orange gel that greatly increases the player's velocity. Objects covered in Propulsion Gel have their friction reduced, causing them to slide around.

Conversion Gel

Conversion Gel is a portal-conducting white liquid made from ground moon rocks. It enables the player to place portals on surfaces that originally are not portal conductive.

Water

Water washes off other gels from surfaces and objects. It has no special properties towards gameplay and does not stick to surfaces.
