Why doesn't this marker cap fit?
Why weren't the kids putting the caps on their colored markers
after using them? I noticed that after unsuccessful attempts to put
on the caps, they just left the markers uncovered. Sometimes even I had
difficulty putting on the marker caps. A closer examination of a marker cap
revealed the problem: both ends of the cap look the same.
At a glance it looks like the marker can be inserted into either end of the
cap. Actually the marker will fit into only one end of the cap.
The incorrect end of the cap does not fit either end of the marker.
The correct end of the cap does have a slightly
raised ring around it, a feature which you may learn to identify.
Initially, however, this subtle clue does not help you get the
cap on correctly.
Design Suggestion
The incorrect end should not appear as if the marker could
be inserted. This could be accomplished most naturally by blocking the
opening on the incorrect end like these other marker caps.
