pH strips are made of a "filter paper like" base paper with pH reacting
reagents for certain pH ranges and, yes, they react improperly after the date
set by the manufacturer.

I got a great laugh from Jackie's comment. However, I don't feel so clever

package. I find it hard to believe the strips will quit working on a certain
date, but we don't use expired reagents in the lab!

I heard of some that went on a graffiti rampage in downtown Chicago last
year . . . . .
Happy New Year.
