The Math Discoverer's Cocktail

The Math Discoverer's Cocktail is a Cocktail that turns you from what is numbers to Holy Crap, I'm going beyond Algebra. It's some Kratom that you taste and it's bitter. Then you take a spoonful of Kratom and mix in warm water and drink. Then, get ready to puke.

Then Math fills your head. Numbers, Equations like 2+3=5 and 3×3=9.

The next day, you try 1g to 6g of Kratom mixed in warm water. No puking unless the dose is too high. More math fills your head. 12×10=120 and 12×11=132. 17+35=52.

The third day, Modafinil 200mg. Algebra and PEMDAS fills your mind. Geometry too.

Day 4, Armodafinil 150mg. More Geometry. Some Trigonometry.

Day 5, Adipex 75mg. Some Pre-calculus fills your head. You begin to calculate percent yield and Mole. The formula for Density or D=M/V goes in your head. Graphs and Parabolas and Lines.

Day 6, Extract Benzedrex with 10ml Distilled White Vinegar and clean the Lavender Oil and Menthol with 15ml Corn Oil. Propylhexedrine Acetate solution (You can't make crystals from Acetate, only HCl). You discard the Oil layer with Lavender Oil and Menthol. You drink 1 Benzedrex. More math and science fills your head.
Day 7, Extract each Benzedrex with 0.2ml Muriatic Acid (30% HCl Acid) in 5.0ml of warm water. Then wash the cotton with 25ml Warm Water each. Then get Charcoal Lighter Fluid and add 15ml of it to the Beaker. Add to a 20oz Soda bottle and shake. Then, use a Ziplock Bag with a small hole cut out and a paperclip. Drain and collect Propylhexedrine HCl and Discard the Charcoal Lighter Fluid layer with Lavender Oil and Menthol. Cook on a Bovado Borosilicate Glass Cooking Dish and tilt to see if a viscous transparent liquid is left. Put it in the freezer for 20 to 30 minutes to initialize crystallization. Then put it next to a small fan or heaterfor 3 to 4 hours for finishing crystallization. Dose range 216mg of Propylhexedrine HCl to 432mg Propylhexedrine HCl. More math fills your head. You start cleaning the house.

Day 8. You have a lab and replaced Charcoal Lighter Fluid with Car Starter Fluid (Heptane and Diethyl Ether) or some Hexane. Higher quality Propylhexedrine HCl.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
