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.

Decorate the windows with gorgeous heart window gel clings for Valentine's Day. Customize the color, shape, and texture with 100% nontoxic ingredients.

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:

Make your own squishy and vibrantly colorful window gel clings using three kitchen ingredients. Taste-safe art and science activity for kids of all ages.

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!

Decorate the windows with gorgeous heart window gel clings for Valentine's Day. Customize the color, shape, and texture with 100% nontoxic ingredients.

For Valentine’s Day we used heart cookie cutters and pink, purple, and red food coloring. We also used healthy doses of pink and purple glitter.

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!

    What a fun idea! (And if it weren’t for my husband, my windows would always be filthy on the outside!)

    How long do these stay good?

    • Crystal February 6, 2016 at 6:17 pm - Reply

      They stay soft and squishy for 3-5 days. After that they dry out and get paper thin, but they are still pretty!

    I run an art club for 10-year olds and definitely want to try this. The recipe says 4 cups of water – could you please give this in millilitres? Just to be on the safe side with differently sized cups. Thanks a lot.

      Yes, of course! 4 cups of water would be roughly 950 mL. I will update this in the post as well. Thank you so much for stopping by and for asking the question.
