When chemistry nerds deliver burns, they don't just hurt—they neutralize you. This shirt brilliantly combines dating standards with acid-base chemistry! On the pH scale, 7 is neutral, anything below is acidic, and above is basic. So if you're a 10 on the pH scale, you're not just basic—you're extremely basic, like drain cleaner or bleach. The perfect comeback for when someone brags about being a "perfect 10" but hasn't opened a science book since high school. Next time someone rates themselves, just ask "on which scale?" and watch their confidence dissolve faster than sodium in water.
