Blue Repulsion Gel to jump higher, the orange Propulsion Gel to run faster, or the white Conversion Gel to allow any surface to accept a portal.
The Weighted Storage Cube is a device used for solving cube-and-button based puzzles in the various Test Chambers found throughout the Enrichment Center.
Here is a sneak peek of what I created for the party...
