Boil water and mix with (1) 3-oz package of Island Pineapple Jello. Mix until jello is completely dissolved. Add 3/4-cup of Malibu coconut rum. Add 1/2-cup of Cruzan pineapple rum. Mix again and pour into 2-oz plastic cups.
NOTE: I found the cups at party city and a similar retailer. I also prefer plastic versus paper. Each package of jello makes approx. (16) 2-oz cups. Fun for the whole family...
