Jell-O Rainbow Ribbon

Prep Time: 3 hours, Chill time: 4 hours or overnight
5 small packages of jell-o, any flavor
6 1/4 cups boiling water
1 cup sour cream, plain yogurt, or vanilla ice cream

1. Dissolve 1 pkg Jell-o in 1 1/4 cups boiling water.
2. pour 3/4 cup of the jell-o into jell-o mold. Chill about 15 minutes (or put into the freezer to chill faster.)
3. Chill remaining jell-o in a bowl until slightly thickened; blend in 3 TBSP of the sour cream. Spoon over jell-o in mold. Chill about 20 min.
4. Repeat with remaining flavors.
5. I let each flavor cool a few minutes befor pouring it onto the previous layer, otherwise the hot jell-o will disolve some of the set jell-o.
