I picked up a fun gelatin mold the other day. It’s a brain. I mainly got it because I’m Left Brain Craft Brain, you know, and thought it would be fun for Halloween. Then I realized how much fun this could be for The Babe. So every other day we pull the brain out along with some new supplies! Ice, baking soda, play dough… You can use them for Halloween or Mad Scientist parties. Or you can use them to actually learn a bit about the parts of the brain. Either way, get ready fore a lot of messy fun!
Slime Play Brain Surgery
First up is slime play with the brain mold. Because I don’t know about you, but I always have assumed a brain is pretty dang slimy. The Babe used the leftover slime from our Sunset Slime project (recipe included). The amazing thing was that after a few weeks, the colors had faded to a perfect shade of brain.
What you need:
- brain mold

- slime
- tools to slice and dice

Ice Play Brain Surgery
This one may have been the grossest of all the brains. It was just ice play with a bit of salt and colored water. But once that red water hit the bin, ewww… Perfect for Halloween!!
What you need:
- brain mold
{affiliate}
- bin to contain the mess
- water
- salt
- food coloring
- syringes
- small containers for colored water
- Pour water in mold and freeze for 3-4 hours or until solid.
- Put out bowls of salt and colored water with syringes to play with and to help the ice melt faster.
Parts of the Brain and their Function
This is a great opportunity to teach older kids about the parts of the brain and what they do. Lay out six different colors of play dough and talk them through the different areas of the brain.
The brain is made up of distinct areas where various functions are processed and controlled.
- Cerebrum: Includes four parts called lobes.
- Frontal lobe: Manages decision-making, problem solving, control of purposeful behaviors, consciousness and emotions.
- Parietal lobe: Receives and processes sensory information from the body. Manages comprehension and the process of letters becoming words and words becoming thoughts.
- Temporal lobe: Manages visual and auditory memories, language and some hearing and behavioral aspects.
- Occipital lobe: Controls vision processes.
- Cerebellum: Controls basic body functions such as balance, posture and coordination. Also called the “Little Brain” because it is believed to be the precursor to the human brain as it exists today.
- Brain stem: Controls essential life functions such as breathing, blood pressure and heart beat.
Also, I figured this is the best time to chat about that whole Left Brain Right Brain thing… The brain is separated into two hemispheres, the right and the left. Historically, scientists have believed that logical thought is controlled by the left side and creative thought on the right side. But more recent research has shown that many processes tend to use both sides of the brain. For example, mathematical thought was believed to be controlled solely by the left hemisphere. But in reality only fact retrieval and exact calculations are managed on the left. Numerical estimation and other math deductive processes appear to require both sides of the brain. Hmm… maybe I need to rethink the name of my blog ;)
Play Dough Brain Surgery
What you need:
- brain mold
{affiliate}
- play dough (you can use our recipe here) – 6 different colors
- tools to slice and dice
{affiliate}
- Press play dough into the inside of the brain mold. If learning about the regions of the brain, follow my diagram above. (Do not follow my example in the picture on the left. Getting the colors in the right places was a curiously difficult, spatial awareness exercise that The Babe and I did not get right the first time!
- Carefully pull away the play dough from the inside of the brain. Then place on the upside down brain for support. I used a balled up dish towel to support the dough while I was moving it.
Vinegar and Baking Soda Brain Surgery
This is your standard science activity of baking soda and vinegar with a brainy twist.
What you need:
- brain mold
{affiliate}
- bin to contain the mess
- baking soda
- vinegar
- Fill brain with vinegar and freeze until solid 3-4 hours.
- Fill bin with several cups of baking soda. We used about 3-4 cups of baking soda to make it extra bubbly.
- Place frozen brain in a bin of baking soda. It may take a bit for the reaction to start, but once it does, there’s tons of foamy fun. Be sure the brain is frozen completely or this activity will go really quickly as the vinegar empties into the baking soda and starts the reaction right away (can you guess that this may have happened to us?).
And yes, my daughter does have a jaguar costume on with her safety glasses. She loves dress-up! Plus didn’t I tell you this is perfect for Halloween parties ;)
Gelatin Brain Surgery
After all this play, we decided we were hungry :) So we played zombies and ate some Jell-O brain. And then played with the leftovers.
What you need:
- brain mold
{affiliate}
- bin to contain the mess
- 1 6 oz box Jell-O
- gummy worms
- spoons
- Make Jell-O according to package instructions and pour into mold. Refrigerate until set.
- Once the Jell-O has set, dip outside of mold into a bowl of hot water to help loosen the brain. After the brain has loosened around the sides (approximately 30 seconds), place plate on top of mold and invert to remove the brain. If it doesn’t come out, repeat the hot water dip and invert again.
- Insert gummy worms into the brain or arrange around it on the plate.
- To play with leftovers, pour brain into a bin. Have towels ready because this is a sticky one!!
Whew! Long post today, but this was literally the play that just kept on going. If you have more ideas on ways to use one of these brain molds {affiliate}, let me know in the comments!
Oh, my hubby would love to have that mold for his class projects! :)
It’s a super fun and not too expensive item. What does your husband teach?
I have to confess that I was never tempted to play brain surgeon as a kid, but I’ll keep this in mind in case one of my kids gets into it! Very fun ideas!
Ha ha. Me neither. Way too skeeved to be a doctor! So engineer it was :)
This looks like a fun activity. I know that kids learn when they can play or use hands on projects. Thank you for sharing, I shared this on Pinterest too.
Thanks so much for sharing! Hope the kids have fun.
What a fun mold for learning about the parts of the brain!
We love it! Especially now that Halloween is coming…
Neat! This looks like a lot of fun!
Thanks! It was a lot of fun. We keep pulling the brain out to play more.
I love this, its totally gross, hilarious and really educational at the same time :D Off to share it on my FB page now x
Thanks so much! Glad you found the humor in it too :)
What a brainy activity! I can guarantee my teen even gets in on this one. Thank you soo much for sharing your genius ideas with us. This mold is priceless!!! Happy Haunting
Thanks for stopping by! Glad to hear this one is good for teens too :) Happy Haunting to you too!
Delightfully gross. As soon as I get over my squeamishness, I’ll try to pick up this mold. I love the different colored play-doh to indicate the areas of the brain.
As gross as the bloody ice hands? ;)
Just wondering (1) how long the slime takes to set up into the mold, and (2) how quickly it collapses once out of the mold? Trying to use this as a party activity. Thanks!
Hi Eve. It doesn’t take very long to set, I think we just pushed it into the mold for 10 seconds or so. But it does start to spread out pretty quickly too. It looks like a brain for at least a few minutes, but you won’t be able to pre-set them before the party.
I was wondering if I could use a picture of yours in my new YouTube channel that I’m making. Please let me know soon, I just loved it so much and I thought it was perfect for the the channel I want to create!
Hi Sam, unfortunately, I utilized purchased clip art to make the image and my license is not transferable. Sorry!
Ouu i never imagined my kids playing with Brain Surgeon , but that’s look cool, i will let my kid to play with brain surgeon so she can get attached with medical things and probably one day she will be a doctor , who knows , :)
Thanks
Thanks for stopping by Anna! I love the idea of inspiring your kiddo :)
This is awesome!! I’ve had to pull my son to homeschool him due to a serious concussion… we are all over brain study right now ;-) Thank you!
Thanks so much. I’m so glad I could help!!!
