Grab your baking soda and vinegar! We’re making a frozen Halloween hands science experiment that kids go crazy for.
What is a frozen Halloween hands science experiment?
It’s your newest favorite Halloween activity. 😉
Prep these ahead of time for a pop-it-out-of-the-freezer-and-it’s-ready-in-minutes activity to delight your little scientists.
Bonus: you don’t need anything fancy to make these.

I made the frozen Halloween hands science experiment on a whim, and they’re epic
It’s a tale as old as time…it was late at night, I was getting ready to go to bed, and stopped in my tracks and thought, “Wait, I should freeze baking soda and water in a glove for science” and then made a u-turn back to my kitchen.
Some of the best thoughts come in the shower.
Some of them come when you’re 16 seconds away from going to bed.
I LOVE this job.

- Baking Soda

- Eye droppers or spoons – eyedroppers are inexpensive and great for fine motor practice
- Liquid watercolors or food dye – optional
- Small Halloween toys or gems – optional
1. First, make and freeze the frozen hands
Make a mixture of half baking soda and half water (just eyeballing it, no need to measure) and stir to combine.
Pour your mixture into a plastic glove.
If you want to add in small Halloween toys or gems, add them in now, then tie the glove and freeze.
Note: When removing the glove, one of my frozen hands lost some fingers because the fingers were too close together in the freezer. If possible, separate the fingers when it freezes for easier glove removal.
2. Next, time for sizzling science
Add a small splash of coloring to your vinegar, making as many colors as you love.
Slowly and gently peel off and remove the glove from the frozen hand. Don’t fret if you break a finger or two in the process – kids won’t mind!
Provide your child with colored vinegar and invite them to squirt or spoon it onto the frozen hands.
An important note about the sizzles
Because the baking soda is mixed with water, these don’t have big, huge sizzles. Instead, the subtle sizzles make the frozen hands last MUCH longer.
If you did an experiment like sizzling apple science, there is much more baking soda used, and the sizzles are much bigger, but it also dissolves and ends faster.
I think of these hands as a mix where you have the slight but cool sizzle of baking soda and vinegar with the longevity of ice excavation.
As Hannah Montana would say, 🎵it’s the best of both worlds. 🎵
How do you make an ice science experiment?
No baking soda and vinegar? No problem!
You can fill your plastic gloves with water, coloring, and trinkets if desired.
Then, instead of using vinegar, provide your child with colorful, warm water to melt the hands.
Using water is less expensive and just as easy to make.
I recommend letting them freeze overnight so they’re totally solid.
Because they use a mixture with a lot of water, they don’t dissolve as quickly as straight baking soda. Mine lasted over 30 minutes.
Use what you do have! Think silicone cupcake molds, ice cube trays, small plastic bowls, etc.
Frozen Halloween hands science experiment gets two frozen thumbs up
We always love an activity waiting for us in the freezer that takes no time to prep before it can be played with.
