Touch everything

Explanation based on my own experience:

I can't find something. It's literally right in front of me, but there is a mix of things and I JUST DON'T SEE IT. Grr.

I start on one side and start touch everything one at a time until it somehow magically appears. It was there the whole time.

If I sense that this type of thing is happening and I'm looking only visually, it's not there. It's just not there.

Touch works better than eyes.
