Add 1 small packet sugar free jello to 1 cup of boiling water, whisk for a few minutes until powder is dissolved. Add 1 cup of cold water, and while whisking, add one packet of Spark, and stir for what feels like forever until every single clump is dissolved. Cover and refrigerate until set. Enjoy and then go for a run or just go be awesome.
Note: I used sugar free strawberry jello with Mango Strawberry Spark
