A delicious, but dangerous concoction of Crystal Light mixed with Everclear that is often confused for flavored water, which makes this drink highly portable and great for drinking incognito.
To make this tantalizing beverage:
mix a Crystal Light On the Go pouch in the flavor of your choice with approximately 20 oz of water.
Add your dose of Everclear and a few ice cubes. Enjoy.
WARNING: drinking too much Crystal Clear may result in people realizing that you are, in fact, drinking something other than flavored water.
