Duck Tape brand glow in the dark tape on the entry steps

I wanted the steps to stand out a little more in the dark so I bought some Duck Tape brand glow in the dark tape 10 ft for $4.97 at Walmart. I put three strips around the hand rail and a long strip on the top and bottom steps I will also and some on each end of the second step that has a rug on it.

And here it is as it is getting dark.

This stuff does work, how long will the tape hold up I don't know yet we will see.
