PHOENIX, Az. (WFLA/KPNX) – Wednesday was the hottest day of the year so far in Phoenix, Arizona.

How hot, you ask?

It was so hot in Phoenix that a box of crayons melted in just 30 minutes.

That’s what happens at 116 degrees.

In an experiment at KPNX, someone glued crayons to a canvas and let the heat do its work.

The dark colored crayons melted first, as they absorbed the sun’s rays at a faster rate.
