Science Juice is a glowing liquid substance seen pumped through conduits throughout Quadwrangle Manor. An energy source, superconductor, and able to amplify electric frequencies, it is stored in IDS Batteries and used by IDS Receptacles to widen interdimensional rifts allowing someone holding an IDS Device to pass into alternate dimensions. It is also used as a source of material for DOLLIs cloning abilities.
Science Juice is a blue substance found in the Evidence Room in Danger Force Season 2 Episode 25 BrainStorm or Bose tries to Drink the Science Juice and It is later used to create a Truth Ray making Danger Force Reveal their Secret Identities to their moms.
Professor Quadwrangle also points out that Science Juice is radioactive, flammable, and also not safe to drink. It is also apparently not safe to touch with bare skin, due to the fact that even partially touching it causes blueball to your testicalls.
Science Juice comes from an undisclosed biological source. Due to the Professor's tone when stating this, it is most likely quite disgusting.
