“This recipe requires a sleeve of Petri Dishes, but won't let me include that in the Ingredients, since they are not food. Petri Dishes can be purchased from Amazon in packs of 20 for --$10, if you can't find them locally. Originally seen in Parents Magazine, Oct 2011, Pg. 148-9 under the name "Germy Jigglers". Those were without the vodka, of course!”

Ingredients Nutrition


  1. Toss your bottle of vodka in the freezer, ice cold works best.
  2. Choose some nice contrasting Jello colors for maximum effect. Pour each packet of jello into a separate bowl.
  3. Boil ~3 cups of water and pour 3/4 cup of boiling water into each bowl.
  4. Stir vigorously until all powder is dissolved.
  5. Add 1/2 cup cold water/cold vodka mixture. (The ratio is up to you, but together they should total 1/2 cup.) I usually do 1/4 vodka and a 1/4 water and they are very firm when done, so you can certainly increase the vodka, if you wish. Just remember the more vodka, the softer the end product.
  6. Pour into dishes (there is a line around the dish that you don't want to fill past).
  7. Place in the fridge for ~1 hour with the lids off.
  8. Make your microorganisms: Pour 1/4 cup water into a small microwave safe dish.
  9. Sprinkle the gelatin packet (I use Knox) over the water and allow it to absorb for 5 minutes.
  10. Microwave for 20-25 seconds to dissolve gelatin.
  11. Stir in the sour cream, mix until smooth.
  12. Pour mixture into a ziploc and allow to cool, kneading from time to time.
  13. Mixture should be cool, but still runny. If it's getting to solid just pop it back in the microwave for a few seconds.
  14. Cut a corner of the bag and drip gooey "bacteria" and "fungus" onto your culture dishes.
  15. Top the biggest cultures with some contrasting decorating gel.
  16. Put back in the fridge for another 15 minutes.
