Pour a thin layer into a glass dish or individual cups and refrigerate until set.
Prepare the next gelatin flavor and allow it to cool slightly.
Carefully pour it over the first layer and refrigerate until firm.
Repeat the process with different gelatin colors and flavors.
Continue layering until all the gelatin is used and refrigerate until completely set.
