I'm a big fan of being able to use something for other things that its original intended use. And it turns out dental floss is one of them. It's very helpful in the kitchen!
You can use it for
Cutting Soft Cheeses
Splitting Cake Layers
Cutting a Perfect Slice of Frosted Cake
Halving Boiled Eggs
Dividing Cinnamon Roll Dough
Cutting Cookie Dough
Hanging Herbs or Peppers
So stick that extra pack you got from the dentist in the kitchen drawer so it's within easy reach!
