I love sprinkles. And the fact that this exceptionally easy DIY Petri Dish recipe is exactly 50% sprinkles makes me giddy.

We made these for our Halloween Mad Scientist Party, and they were a huge hit. They also work for a science themed birthday party as a fun dessert or party favor.

Or you could make an adult version and fill them up with boozy jello shots!

How To Make DIY Petri Dish Jello

All you have to do to create your own is make Jell-O per usual (what, you don’t usually make Jell-O?), and then pour it into the petri dishes.

Let them cool in the refrigerator, and give them a dust of sprinkling just before serving them!

Optional: I wrapped the Petri dishes with skull ribbon that I found at Paper Source so that the bottoms of the dishes wouldn’t fall off when someone picked them up. Science or Halloween themed washi tape is another option!

  3. I just made these for my son’s birthday party. I used a Turkey vaster to fill the Petri dishes-it worked great! Thanks so much for sharing your idea?

  4. If you put the sprinkles in right away before the jello sits they will melt to look like mold for Halloween! My 4th grade students loved it! Check out my website for a picture!
