We sometimes debate, you and I, what is or is not "nerdy" - it's silly, really, but it is a part of who we are and what we do, and I wouldn't change that.
Except that if you disagree about THIS being nerdy, you're wrong - teenagers doing a yearlong project to invent something that will solve their lifelong irritation with the fact that there's water in the first squirt of ketchup from a bottle.
I could have saved them time by saying "shake the bottle first." But they invented a gizmo. Check it out, and wonder why a mustard fan didn't come up with it first, since those French's bottles are the REAL offenders.
