Naza Mounting Foam

At the workbench, there were three rolls of foam. Witespy was hungry to Fly.  

He test flew a piece from the first roll.
“This foam is too Soft!” he exclaimed.

So, he test flew the foam from the second roll.
“This foam is too Hard,” he said.

So, he tested the last roll.
“Ahhh, this foam is just right,” and with loops and rolls, he happily lit up the sky.
