Stained Glass Bubble Wrap Window Decoration

As the holiday season hovers all around us, we have a fun color mixing activity that will also use some of the bubble wrap that abounds this time of year. Grab a few cups, some colored water and a sheet of bubble wrap to keep them entertained while color mixing and creating a stained glass window decoration. It’s a kitchen science rainbow!

  • Bubble Wrap (the larger the bubbles, the better)
  • Pipette
  • Food coloring or True Color Tablets
  • Plastic cups
  • Scissors
  • Water
  • Paper towels
  • Tape (to hang your masterpiece)


1. Have an adult cut or pop small holes in the side of each bubble. The holes should all be in the same place on every bubble. This will deflate the bubble, but if you do it carefully, the bubble will keep some of its shape.

2. Tape the piece of bubble wrap with the holes pointing up to a window. Place a few paper towels under the bubble wrap in the window sill to catch the drips. And there will be drips. Obviously, this is an activity to do in an easy-to-clean area. Don’t do this over carpeting. You can also tape the bubble wrap to a piece of cardboard, wipeboard or other flat surface and place it in an area that’s easy to wipe up.

3. Fill plastic cups 1/2 full with water and drop coloring tablets to color the water. We prefer the True Color Tablets, because they do not stain like food coloring.

4. Fill a pipette with colored water, insert it into one of the bubbles via the holes and squeeze the liquid out.

5. Repeat with different colored water mixing different colors in the same bubble.

6. You are done when all of the bubbles are filled and you have a stained glass window! Just be mindful of the colored water and holes when throwing it away.

Note – the bubble wrap we used did not have self-contained bubble pockets, so we were only able to fill them up half way before they poured into the next one. You can fill the bubbles higher if they aren’t all connected. 

This experiment is focused on giving children the space and time to discover the colors of the rainbow. Show them how to do it and then step back. Set up in a child-proof area and don’t worry about making a mess. Sometimes the best learning comes from the biggest mess.

Squishy, Squeezy, Messy, Color Mixing Kitchen Science

By Blog Editor Susan Wells

Some of our most popular kitchen science experiments at Steve Spangler Science involve color mixing and oil and water blobs in Lava Lamps. We came across this fun twist that involves color mixing and oil and water blobs, so I had to try it with my kids…

We started with Giant Test Tubes filled 3/4 full with vegetable oil. I filled small cups with water and let my daughter drop Color Fizzer Tablets into the water to mix her original colors. She then used Pipettes to transfer the water from the cups into the Test Tubes. We watched different color blobs of water fall from the top of the oil down to the bottom. It was a rainbow of colors. As they reached the bottom, some combined with others, while some sat on top of the big blobs.

When the tube was full, we capped it off and she shook it. We watched as the colors mixed and the blob grew. It was fascinating to watch the different colors form a wave inside the tube.

My daughter wasn’t done yet, so I filled some pie pans with enough oil to cover the bottom. She dropped blobs of colored water into the pans and watched them mix. She was busy for a long time pushing the water blobs around the pan with her finger. When the water blobs meet, they combine and create new and different colors.

The Flashing, Color Mixing, One-of-a-Kind White Lightning Stick

By Blog Editor Susan Wells

One of the biggest hits of the summer is the White Lightning Stick. On the Fourth of July, we held a small firework show in our front yard with our neighbors.

Along with the traditional sparklers and black snakes, we also shot off several film canister rockets and Mentos soda geysers. While the kids were waiting for the next activity, they played with the light sticks. Naturally, the sticks were first used as swords and weapons, but as the sun set, they began to really look at the light sticks and made observations.

Create a Rainbow in a Bag – Pinch and Mix Color Mixing

By Blog Editor Susan Wells

I’m occasionally asked by teachers and school groups to bring in a few hands-on science experiments for a class. One of my all-time favorite go -to activity is color mixing with Pinch and Mix goo. Steve Spangler Science sells and all-in-one Pinch and Mix Kit for 30 students or a smaller group. You can also use gel cake frosting if you want to do it yourself.

Start this activity with a literature connection by reading the book Mouse Paint by Ellen Stoll Walsh. Mouse Paint is a delightful story about three white mice who discover jars of red, yellow, and blue paint. Creativity ensues as the mice explore what happens when they begin to play in the puddles of paint. Wondrously, the three primary colors they began with become secondary colors as they play.

Now it is your turn to delight and discover. Discuss what the mice found and what happened after they were coated in one color paint and messed about in another color. Then make your own color connections by pretending you are little mice mixing the colors in your zipper-lock bag!

Squeeze 1 to 2 tablespoons of each color of goo into the bag. It’s best if you place one color in each corner and one in the middle. Then gently squeeze air out of the bag and seal it. Pinch and mix the colors together by blending the primary into secondary colors. The bag will start to take on a soft, stained glass look.

Hold it up to a light or a sunny window.

Some kids will gently and carefully blend their colors, but most will grab and squish the bag until the colors turn army green, grey and putrid purple. Don’t worry about a failed activity; the kids will still find beauty and discovery in their crazy-made colors.

Make sure you keep a Sharpie nearby, because the kids will want to bring home their creations.

Ooey Gooey Science – Lisa Murphy's Color Mixing Madness with Shaving Cream

Who could turn down an opportunity to make a mess with shaving cream and learn about color mixing with the always fun Lisa Murphy? Not me! When I learned that Lisa and her husband, Tom, were planning a trip to Colorado, I asked if she would be a guest on Science Mondays at 9News. The real fun for me, however, was getting to spend down time with Lisa away from the hustle and bustle of a conference. I’m honored to get to consider her a colleague and friend. We laughed about the idea of getting to spend an entire weekend together with a few hundred of our favorite early childhood teachers for something that would probably be well beyond extreme. I don’t think we’d ever be invited back to that hotel. Just a thought…

Watch Lisa in action as she shares one of her signature color mixing demos with shaving cream!
