Calming Sensory Bottles Fill bottle one-fourth to one-third full with light corn syrup. Add mylar (shiny) confetti in the shape or shapes of your choice. Seal tightly using hot glue if available. Why It Is Calming Try it and you?ll see! The syrup glides down the sides of the bottle very slowly; bringing the confetti right along. No wonder this one is sometimes called a Stress Bottle!
