Science Shooters (Or Petri Dish Jello Shots)

"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!"

Ready In:
2hrs 10mins
20 petri dishes




  • Toss your bottle of vodka in the freezer, ice cold works best.
  • Choose some nice contrasting Jello colors for maximum effect. Pour each packet of jello into a separate bowl.
  • Boil ~3 cups of water and pour 3/4 cup of boiling water into each bowl.
  • Stir vigorously until all powder is dissolved.
  • 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.
  • Pour into dishes (there is a line around the dish that you don't want to fill past).
  • Place in the fridge for ~1 hour with the lids off.
  • Make your microorganisms: Pour 1/4 cup water into a small microwave safe dish.
  • Sprinkle the gelatin packet (I use Knox) over the water and allow it to absorb for 5 minutes.
  • Microwave for 20-25 seconds to dissolve gelatin.
  • Stir in the sour cream, mix until smooth.
  • Pour mixture into a ziploc and allow to cool, kneading from time to time.
  • Mixture should be cool, but still runny. If it's getting to solid just pop it back in the microwave for a few seconds.
  • Cut a corner of the bag and drip gooey "bacteria" and "fungus" onto your culture dishes.
  • Top the biggest cultures with some contrasting decorating gel.
  • Put back in the fridge for another 15 minutes.

I love to experiment with new recipes, probably due to my science background, I'm always altering conditions. Nothing is more fun than inviting people over to eat the food I have put together!
