I really, really wanted to use some colorful corn in a few preschool activities recently (more to come on those later). Since I’d never created colorful corn before, I looked online for some suggestions. While there are tons of ideas for preparing, decorating with, and creating with corn, there weren’t too many ideas about HOW to dye corn kernels. So, me being me, I turned it into my own little science experiment. I’m pretty sure my boss, my assistant, and my students all found this process very entertaining!
To clarify, the corn kernels are just regular ol’ popcorn kernels. 🙂
First, I tried the baggy and food dye method. I placed some corn kernels in a plastic baggy, added some food coloring, zipped the bag, and shook everything up for a few minutes. Even though this method works great when I dye pasta and rice, it didn’t cut it for the corn! The corn kernels have a smoother surface than rice or pasta, which is why I think this method didn’t work all that well. The dye stuck to some parts of the kernels but not others, and the color just wasn’t all that great!
Next, I tried adding a little bit of rubbing alcohol to the baggy that held corn and food coloring. Still the same problems. I tried a splash of vinegar too, but to no avail. As I told the kiddos, though, when you’re conducting a scientific experiment you need to try more than one idea. This was also a great way to show the children that not all experiments are a success! 🙂
I kept plugging along until I came upon a method that worked incredibly well for me. To finally create a rich, even color on the corn kernels, I dyed them like I would dye Easter eggs! When comparing the final batch to the original batch, there was a marked difference. The kids and I used all of the corn, even the botched attempts, but I definitely preferred the corn from my final batch!
How to dye corn kernels:
1. Partially fill a cup, container, or plastic baggy with water.
2. Add vinegar to the water (a tablespoon or so).
3. Add desired amount of food coloring to the water/vinegar mixture. Swish to distribute color. I used about a tablespoon for every cup or two of corn.
4. Add corn kernels to the container/baggy. Make sure the liquid completely covers the corn.
5. Allow to sit for a few hours. I let mine sit overnight.
6. Remove corn kernels using a slotted spoon.
7. Let corn dry completely.
Have you ever tried to dye corn kernels?
Here are some of the FUN activities and projects we’ve done using our dyed corn kernels:
- Colorful Corn Mosaics
- Sweet-Smelling Candy Cane Sensory Play
- Christmas Contact Paper Art – A Seasonal Sticky Table
- Rainbow Activity with Colorful Corn Sensory Play
I know that some people are concerned about using food for art/crafts/sensory play/etc. There is a concern that it’s disrespectful towards children who might not be getting enough to eat at home. While I certainly respect this concern, I do not agree. In the past, I have worked with children who weren’t getting enough to eat. As their teacher, and as a member of their community, I did all I could to ensure they were cared for and well-nourished. I would never let a child in my care go hungry, and their needs were (and always are) paramount in my mind. It is still an issue that I concern myself with now, even though my current students don’t have those same problems. The food I use for crafts, sensory play, etc. are often stale or past their “sell by” dates. I take great care to keep the food in sealed containers to use again and again if it’s possible. Please know I mean no disrespect whatsoever.
