Would you try it? Tangy mustard flavor joining the Skittles rainbow

A new flavor is joining the Skittles rainbow.
The candy is partnering with French's to make a new tangy mustard-flavored Skittle.
It's all to celebrate National Mustard Day on Aug. 5.
The new Skittle will only be available at French's vintage yellow bus, called "Mustard Mobile."
The bus will be making stops nationwide -- including one in New York on August 5.
