Playing bubble is my pass time activity with kids. We used to have loads of joy. I wanted to gift my kids with happiness this Christmas with a DIY bubble wand. This will double the joy of Christmas fun and wands matching the occasion!
We have made wands several times for different occasion and trust me there is a learning every time. The physics concepts are learned from this experiment. We try different shape and make it unique every time.

How to make a Christmas Tree Bubble Wand
- green tape
- bubble mix solution
- a cup
- 12″ x 6mm pipe cleaner sparkly metallic green and 12″ x 6mm pipe cleaner furry green
From the list, you can see that there are two pipe cleaners we used namely the sparkly and the furry type. The trees will look different. Both displayed the same performance but my kids enjoyed sparkly one when compared to the furry type.
Instructions to make them
- Take the pipe cleaner and fold it into half and mark the center point which will be the top of the Christmas tree.
- Bend and make a Christmas tree shape by joining the end in the center of the tree base
- Twist the rest of the pipe cleaner around chopstick end.
- Use tape to wrap it and secure it.
- Take the bubble mix in a bowl
- Before blowing check with kids if they know what shape will come out of the wands.
- Dip the bubble wand in the mix and blow
Tisha expected it to come out in Christmas tree shape. But she understood that it will be only round in shape after blowing a couple of times.
Then I explained to her about the science behind it in simple words.
I told her that the shape is a sphere and it is happening due to the push-pull force between air and the bubble mixture.
Later on, my elder one joined us from school and then I gave her a detailed explanation.
I told her that air is present everywhere but not visible and it can be felt. The soap solution reduces the surface tension of the water. When the bubble is floating the air present inside push the bubble outside and air outside pushes the bubble in and hence there is a push-pull force which makes the shape round.
Even with the Christmas tree shaped bubble wand the bubble will be round as the sharp corners will not balance out the inside and outside air. The outside air will push persistently till bubbles become round. Pritika observed that when the bubble landed on a slippery table it change shape to semi-sphere.
I told her that the third force coming from the table makes it appear flat on the table Hence, spherical bubble lands as a semi-spherical one. Pritika tried adding another bubble to the first one to see the shape.
Every time the touching portion appeared to be flat. Rest of the portion was round in shape.
Then we imagined and tried to make many bubbles float around attaching to each other. The bubble in the center will become a cube as all other bubbles touching it will make it flat. Across all sides, the sphere becomes flat to appear like a cube.
She also tried to look at the biggest bubble and its structure. She did eight bubbles on the table. It took time to stack and few disappeared in the process and she managed to arrange 8 of them in one go.
Likewise, she tried in different ways and we enjoyed. Tisha had more fun and less understanding. But Pritika understood concepts and experimented new things.
