The OG Wacky Engineering Logo Tee
Free shipping on orders of $100 or more (United States only).
Welcome to your new favorite shirt—the same one we wear when we’re breaking stuff, fixing stuff, and asking, “What if we just added more voltage?”
This is the official Wacky Engineering logo tee. Clean, simple, and proudly rocking the full logo so people know you’re into weird builds, clever hacks, and questionable experiments that somehow work. It’s the kind of shirt that says, “I watch YouTube for the science and the chaos.”
Details for the detail-oriented:
• 100% ring-spun combed cotton (aka soft enough to sleep in, tough enough for the shop)
• Lightweight 4.3 oz fabric with a slim, modern fit—like those American Apparel classics but better
• 90% cotton / 10% polyester, for that extra touch of stretch
• Feels good, fits great, and lets you look slightly more put together than your last project
Model is 6’0” and wears a size L, probably while testing a questionable motorized contraption.
Why you need this:
Because supporting Wacky Engineering means more wild ideas, more builds that probably shouldn’t exist, and more fun doing it anyway. Also, it just looks cool.
