We love sprinkles.

And the fact that this exceptionally easy DIY Petri Dish recipe is exactly 50% sprinkles makes us 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!

Ingredients and Materials Needed to Make DIY Petri Dish Jell0

How to Make DIY Petri Dish Jello

Step 1– All you have to do to create your own is make the Jell-O per usual as instructed on the box.

Then, pour the mix into the petri dishes. 

Let them cool in the refrigerator. 

Step 2 — And give them a dust of sprinkling just before serving them!

You can sprinkle in some candy before you allow the Jell-O to cool. Just be aware that the sprinkles may ooze out some coloring when wet.

Optional: We wrapped the Petri dishes with skull ribbon that we 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!

  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!5 stars
