[CW Flash] To hell Barry get drunk the gang creates a "500 proof" drink. How can something be 250% alcohol?

Edit : To help*

To be fair, Caitlin says "It's *basically* 500 proof." in that scene, and didn't say it was a literally impossible drink. What she did was probably make a solution of lab-made moonshine first (so she could precisely measure the amount of alcohol), and then mixed in a few other compounds and substances that are known to create impairing effects in tiny doses. She then increased the dosage of said substances to fatal levels for a regular person. But she knew Barry could metabolize super fast, and successfully gambled that he'd feel buzzed for at least a short time.
