Incredible Growing Gummy Bears

Here’s a fun experiment that hardly takes up any room, isn’t messy, and your kids will love it!

Here’s how we landed on this experiment: We stopped at the drug store for baby wipes, and 3.5 year old N bombarded me with five minutes of this… “Mom, stop! You have to see this. Mom, can you get me this light up candy cane/cup shaped like a fairy/snow globe. Wait!!! I really want it!” I normally adore her enthusiasm, but I have a short wick for the begging and pleading for random odds and ends. Pair that with a toddler who insists on standing in the shopping cart and you get the picture of me yearning for a hot cup of coffee and a copy of US Weekly! If you ever wondered if I’m actually raising independent thinkers, the answer is most definitely “yes!” So, on our way to the check-out, we walked down the candy aisle. Dumb move, I know, and N quickly managed to pull a bag of gumdrops off the display with a request to make gumdrop sculptures. 

Ack. She knows my weak spot for creative projects! Um, yes, we can buy the gumdrops for the sake of your growing mind. And with that, she also pulled down a pack of gummy bears. I remembered reading about a gummy bear experiment, and that’s how we ended up bringing these little jelly woodland creatures home with us.

The experiment is easy. We each had to eat one, of course, and then N chose a couple to add to the water. I asked her what she thought might happen to them after being submerged, and she said she didn’t know. After a couple hours we checked on them, and found them covered in tiny bubbles. We compared them to one of the dry originals, and the wet bears were a bit plumper!

I left N in the kitchen while I put her baby sister down for a nap, and returned to find her nibbling on one of the plump bears!! She had this to say, “I know I wasn’t supposed to eat the bear, but I had to also compare the way they taste to see if they tasted the same.” How could I be upset with that?

In all, we let the bears sit in water for three days, and you can see the size difference in this image. The gummies kept expanding and then finally seemed to fall apart. If you try this at home, and want to do a taste comparison, be sure to refrigerate your gummy bears so they don’t grow bacteria. Yikes!

The Science behind the Experiment

Gummy bears are made up of water, sugar, and gelatin. Like a sponge, gummy bears will absorb water but the gelatin keeps the bears from dissolving in the water.
