Combine the lychee, egg whites, rum, lime juice and simple syrup in a shaker, and shake vigorously for 10 seconds. Add some ice and shake for 5 seconds. Add the soda water to a highball glass and slowly double strain the shaker contents into the glass. The egg whites should rise 1/2- to 1-inch above the rim. Dust the top with cinnamon to serve.
