PHOENIX -- The 3TV Forecasters say it's going to be the hottest day of the year -- so far.
They're calling for a high of 112 degrees. The National Weather Service has issued an Excessive Heat Warning, the second of the year. It's in effect 10 a.m.-8 p.m.
We wanted to know how long it would take 600 pounds of ice to melt in such extreme heat.
To find out, we got two 300-pound blocks, the biggest Ice King makes, stacked them one on top the other and put them in our parking lot.
Instead of watching grass grow or paint dry, we're watching ice melt.
The experts at Ice King say the ice will last through the weekend. What do you think? Share your prediction in the comments area below.
