Piranha solution is a super corrosive mixture of 30% hydrogen peroxide and sulfuric acid, and I decided to make it even stronger. By swapping the regular 98% sulfuric acid for 165% sulfuric acid (aka, oleum), an entirely new mixture is formed with PURE hydrogen peroxide, PURE sulfuric acid, sulfur trioxide, and a mix of peroxysulfuric acids. Truly horrifying, fairly unstable, and extremely corrosive. The oleum was made by heating sodium bisulfate (pH-low for pools) up to 500C to convert it to sodium pyrosulfate and water, and then ramping up to 800C to create sodium sulfate and sulfur trioxide. This process was discussed on Science Madness, and I figured it was worth investigating, since the ingredients are dirt cheap, and because I built an electric kiln a few years ago (and recently upgraded it)! This video was just going to be about the oleum and sulfur trioxide, but the oleum piranha was too good to leave out! Wanna help support LabCoatz?

Highly concentrated piranha solutions are bad enough, and can be explosively unstable. This "barracuda solution" is essentially PURE hydrogen peroxide mixed with extremely corrosive oleum. Nearly everything shown in this video is highly corrosive and capable of causing severe chemical burns. 0:00 Piranha solution is scary 0:22 ...but not scary enough 0:36 Sulfur trioxide 1:41 Sulfate pyrolysis 2:15 Making oleum and sulfur trioxide 5:08 Making oleum piranha solution 6:16 Paper vs. oleum piranha (barracuda solution?) 6:48 Sugar reactions compared 7:39 Barracuda and ethanol 8:07 Barracuda solution vs. flesh 8:53 Wrappin up...you'd better stick around!
