Here’s a fun kids Halloween party game or Halloween kids activity that doubles as a cool science lesson: Freeze glow-in-the-dark bouncy ball eyeballs (affiliate) in baking soda and water, and then have kids spoon vinegar on top to reveal the eyeball surprise! It’s a great way to put the STEAM into Halloween!
Check out the bubbling vinegar as it hits the baking soda eyeball in a science reaction…
Remember the Rescue Han Solo from carbonite kids game that we played at Elise’s Episode 6: Return of the Birthday party? This easy Halloween game is a riff off of that game that was a HUGE hit!
This time instead of Star Wars minifigures, I hid these glow-in-the-dark bouncy ball eyeballs and encased them in baking soda using this baby food freezer tray. Halloween party guests start off with a small bowl of vinegar with a spoon, and a mysterious white ball on their plate. Ooh …what’s inside?!?!?
It’s a super fun and easy kids Halloween party game that brings the smiles.

How to make a fun kids Halloween party game: Eyeballs surprise science experiment
Step 1: Make the frozen eyeballs
We used the same recipe from my free Han Solo from carbonite game that we played at Elise’s Star Wars birthday party. This recipe is easy enough that kids can do it on their own.
You’ll need a big box of baking soda and a larger ice cube tray – I like this baby food freezer tray that I still use now that my kids are older to make purees for this sweet potato crackers recipe and other recipes. Freeze as directed and then store in the freezer until party time.
Step 2: Pour vinegar onto the frozen baking soda eyeballs
Give each party guest their own plate, bowl of vinegar, and a spoon and uncover the secret mystery!
Step 3: Play with creepy bouncy eyeballs
Rinse off the bouncy eyeballs and then use them for your next kids Halloween party game.
