Did you know that you can make square bubbles? We tried it this week and it was so much fun! My kids played with them for such a long time. Read on to learn how to make these awesome square bubbles.
It is really easy to put these together. You should definitely give it a try sometime.
We all know how to blow regular round or spherical bubbles. Little kids can’t get enough of them. You use a bubble wand and blow a bubble through it to create a circular bubble that floats away. No matter the shape of your bubble wand, the bubble is still round when you blow it. This is because the round shape is the smallest amount of surface area needed to enclose that amount of air.
These square bubbles are a bit different. There is no blowing. It is created by dipping a cube into a pot of soap solution.
How to Make Square Bubbles:
To make these square bubbles, you need just a few supplies:
6 Pipe Cleaners– cut in half
6 Plastic Straws– cut in half
Large pot or bowl that is deep enough to but the cube into
Warm soapy water for the bubble solution. We used liquid dish soap.
To start, twist three of the pipe cleaner halves together making it into a pyramid type shape. Repeat that step four times.
Next, put a piece of straw onto each one of the pipe cleaners.
Finally, attach each 3-piece section to another section by twisting the corners together. This will form it into a cube. The cube is your bubble “wand”.
Now you will need to fill a big pot or a deep bowl with warm soapy water. Make sure to add a large amount of soap to create the best bubble film for your bubbles.
Dip your bubble cube into the water. Make sure to submerge it all the way under the soapy water solution. Slowly pull it out to see the square bubbles form. You’ll be able to see the surface tension creating the bubbles as you pull them out of the water.
Repeat again, and again, and again . . .
Why and how does it work?
You will see there is a center cube bubble. Also, each edge of the cube has a bubble across it. The bubbles along the side push the soap film into the center bubble making it a square shape.
If you pop the sides the center one will be round. The sphere is the easiest and most stable shape that bubbles can form but it can turn into other shapes when it is surrounded by other bubbles.
Try other shapes to see if they work, too!!!
