Ever had so much fucking time in your life and really like the taste of hospital food? Then go buy a 6oz box of blue, yellow and red jello plus a box of knox gelatin. To get these fabulous layers, mix the blue jello with an envelope of the knox gelatin. Pour in two cups of boiling water. Dissolve the gelatin. Add 1/2 cup of ice. Stir until thick. Remove any remaining ice cubes and any bubbles that may have formed. Pour into a 9×13 inch pan. Let set in the refrigerator.
Repeat with the yellow jello and pour it over the set blue. Repeat with the red jello and pour it over the yellow. And there you have it, Rainbow Jello, and a whole day blown.
