It’s Lick-A-Stick From Lick-M-Aid’s Fun Dip Packs!
Fun Dip is a candy manufactured by The Willy Wonka Candy Company, a brand owned by Nestlé. The candy has been on the market in the United States and Canada since the 1940s and was originally called Lik-M-Aid. It comes in many different flavors with candy sticks that are included.
Fun Dip is similar to fellow Wonka product Pixy Stix, but sold in small pouches, rather than paper or plastic straws. When called Lik-M-Aid, it consisted of 4 packets of flavored and colored sugar. When rebranded in the 1970s as Fun Dip, two edible candy sticks called “Lik-A-Stix” were added. While the original flavors consisted of lime, cherry and grape, the most common flavors are cherry, grape, and a raspberry/apple combination that turns from blue when dry to green when wet with saliva or water. It also comes in sour flavors, including sour watermelon, sour apple, and sour lemonade. There is also orange flavored Fun Dip. Packets with one stick and two flavors were once the standard, and packets with only one or two flavors are still available with less prominence than the now-standard three-flavor package.
