​​

What You Might Already Have in Your Closet:

• Button-up shirts, turtlenecks, or hoodies

• Lab coat or any oversized white button-down shirt

• Khakis, cargo pants, or old jeans

• Toolbelt or pocketed utility vest

• Blazer or cardigan (for the “tenured professor” look)

• Graphic tees with ironic slogans or science puns

• Sneakers, boots, or scuffed dress shoes

 

Hair & Makeup Tips:

• Inventor: Messy hair, teased with dry shampoo or hairspray. Bonus points for gray streaks!

• Hacker: Hood up, sleek ponytail, or bedhead. Smudged eyeliner adds intensity.

• Lab Scientist: Tidy bun, hairnet, or practical cut. Add “chemical smudges” with eye shadow.

• Engineer: Practical and slightly unkempt. Grease smudge on the cheek or a pencil stuck behind the ear.

• Optional: Fake bandaids, dark circles under the eyes (for that "I haven’t slept in 3 days" look)

 

Accessories & Props:

• Safety goggles or tinted science lab glasses

• Clipboard, blueprints, schematics, or circuit boards

• Tablet, laptop, or old keyboard

• Flasks, beakers, syringes (just for fun — keep it safe!)

• Headlamp, tool kit, or screwdriver

• Flash drive labeled “TOP SECRET” or a notebook full of formulas

• Name badge with intimidating credentials or a nonsense acronym lab

 

Behaviors, Voice, and Quirks:

• Hackers: Rapid typing, distracted muttering, sharp eye contact. Speak in acronyms and phrases like “firewall breach,” “backdoor access,” and “I left breadcrumbs in the source code.”

• Inventors: Wild gestures, sudden “aha!” moments, trail off mid-sentence as you invent something else. Overuse words like “prototype,” “breakthrough,” and “temporarily unstable.”

• Engineers: Logical speech, precise diction. Over-explain things. “Well, technically…” is your favorite phrase.

• Scientists: Add a verbal tic like “Interesting…” or “Hypothetically speaking…” You may randomly stare off while calculating something in your head.

• Add quirks like constantly measuring angles, tapping your pen, scribbling equations, or reacting dramatically to “improper use of units.”

Whether you're the one who built the murder weapon, hid the evidence in the code, or accidentally triggered the chemical reaction, the “Brains Behind the Blueprint” characters are funny, brilliant, and just maybe dangerous. You're not just solving the mystery—you might have engineered it.
