Did you know that you can make your own gorgeous heart window gel clings for Valentine’s Day? Customize the color, shape, and texture using 100% nontoxic ingredients to make the most squishy, translucent, and colorful window gel clings! In addition to making a beautiful Valentine’s Day decoration, there is plenty of Valentine’s Day science to learn from making these as well.
My favorite reason for making these squishy window gel clings is that they can be fully customized! We have now made spring/summer window gel clings, Halloween jellies, and Christmas gel stickers. Our house looks naked without gel clings in our windows.
Heart Window Gel Clings for Valentine’s Day

To make our heart window gel clings we gathered these supplies:
- Four cups of boiling water (about 950 mL)
- Six packets of unflavored gelatin (about 43 grams)
- Food coloring and glitter of your choice
- Googly eyes and/or beads, if desired
- One large cookie sheet with a rim
- Cookie cutters
After gathering our supplies we followed these directions:
- Add gelatin all at once to the hot water. Use a whisk to stir to make sure it all dissolves. Spoon out any bubbles.
- Pour the mixture into the baking sheet. You want it to be about a quarter of an inch thick (½ – ¾ cm). It doesn’t have to be exact, but make sure it is level.
- Once the gelatin mixture has cooled a bit (10-15 minutes), have fun dropping food coloring into the gel and swirling it around with a toothpick. For extra flare, sprinkle glitter over the top or add a few beads or googly eyes. You probably only have about 30 minutes before the gelatin starts to harden, so don’t dawdle!
- When you are done decorating, let the gelatin harden for at least a couple of hours. Leaving it out uncovered overnight yields the best results.
- Once it has set, use cookie cutters to cut out shapes or cut out your own shapes using a butter knife.
- Use a spatula to carefully lift the gel shapes out of the pan. Don’t worry if they tear because you can simply mold them back together on the window. Stick them onto the windows and enjoy!
Valentine’s Day Science
Making heart window gel clings is a fun and creative way to spend time as a family, but there is so much to learn as well! For example, notice how the gelatin gets thicker, or more viscous, as it hardens. You will notice that the colors don’t spread as easily as the gelatin sets.
Also take notice how the window gel clings start off thick and squishy, but within a few days on the window they become paper thin and crusty. This is because water is evaporating from them. Making these nontoxic decorations can give children some of their first hands-on science experience!
