Mix milk and pudding in bowl for 2 minutes.
Divide into 3 equal portions.
Color 1 portion red with about 15 drops of food coloring.
Color 1 portion blue with about 15 drops of food coloring.
Transfer each color to a zippered sandwich bag.
Clip the corner of the blue and pipe it equally into the bottom of 5 3 oz Dixie cups.
Lift and gently tap each cup on the counter to level up the pudding.
Repeat this process with the white and then red colors.
Insert a Popsicle stick in the middle of each cup and place in freezer for 4-5 hours or until firm.
