My daughter Haylee is pouring 12 cup of vegetable oil with 2 tablespoons water 810 drops of food coloring and 1 tablet of alka seltzer. We did this at the dinner table right before lunch, and it takes about 8 minutes from start to finish. It is super easy to do and clean up. It doesn't make a mess. We suggest using a different container to empty out the cup of oil when cleaning up and rinsing with soap and hot water.
