I've got long hair (not as long as yours. Impressive btw!) and I've found if you're willing to take the time to wash it out, sticky stuff can be fun like chocolate and caramel, honey and syrup, molasses and treacle (for those in the UK), and if you wanna go super sticky stuff like fluff or peanut butter!
If you want some good starter stuff I would say pies, cakes, batters, syrups, and creams can be good for that.
Love you, too
