Why didn't the water spill over the glass? Well, the surface tension was strong enough that it just went around your finger. The water molecules still stuck to each other and nothing spilled! What happened when you put your soapy finger into the water? The soap on your finger broke the water's surface tension and some of the water molecules didn't stick to each other anymore and they were pushed out of the glass!
The force of surface tension also creates bubbles. In plain water, the surface tension is strong and the water might make some bubbles, but they will not last very long and they will be very small because the other molecules in the water will pull on the bubbles and flatten them. Soap needs to be mixed with the water to make bubbles that can float through the air.
When you add soap, the water becomes flexible, sort of like elastic, and it can hold the shape of a bubble when air is blown into it. After you make the super bubble solution and let it sit for at least one day, try doing some of these cool bubble tricks!
Can you think of any of your own tricks to do with bubbles? The bubble was round even though it came from a square! Bubbles are always in the shape of a circle when they detach and float through the air because the skin of soap always tries to take up the least amount of space it can and still keep the same amount of air inside the bubble. The soap molecules always stretch into a round shape automatically! A round shape takes up less space than a square shape. Try the trick again, but make a wand in any shape you want - what about a star or a triangle?
Do bubbles from those shapes become round too? You should have been able to push the scissors through the wall of the bubble without popping it! When something wet touches a bubble, it doesn't poke a hole in the wall of the bubble, it just slides through and the bubble forms right around it.
The bubble solution on the scissors filled in the hole that would have been made. If you try poking dry scissors through your bubble, you will see it pop instantly! If it popped when you put the wet scissors in, something was probably too dry. Try it again and make sure anything that touches the bubble is completely wet with bubble solution.
For another trick that works best, get one hand completely wet in the bubble mixture then use the other hand to hold your bubble blower and blow a huge bubble in the palm of your wet hand. Molecule - a very tiny part of a substance that is too small to see with your eyes.
A water molecule is smaller than one drop of water! Surface tension - molecules in a liquid are attracted to each other and make the top of the liquid very tight. The surface tension is what causes water to form drops. It also makes a dome shape across the top of a container that is filled to the top.
Evaporate - when a liquid dries up and goes into the air. The liquid is then in the air, but it is a vapor or a gas now and you can't see it. When we say the air is humid, it means that a lot of water has evaporated into the air, and now water vapor gas is floating around in the air. It makes the air moist and heavy, and it might make you feel sticky when you go outside. Bubbles are pockets of soap and water that are filled with air. When soap and water are mixed together and the air is blown into the mixture, the soap forms a thin skin or wall and traps the air, creating a bubble.
Soap bubbles are not the only kind of bubbles. You can find bubbles in lots of liquids. You might see small bubbles in plain water, but they will always be in the water or floating on the surface of the water, not floating through the air. There are bubbles in soda pop, too. The special thing about soap bubbles is that they can float freely in the air; they don't have to be touching water or another liquid like most bubbles do.
Can you find other bubbles around your house? What about something that is round and filled with air like a bubble? Some examples are balls, balloons, and bubble wrap. How does soap help make bubbles out of water? Soap makes the surface tension of water weaker than normal. It also forms a very thin skin that is more flexible than water. When the air gets trapped under the surface of the mixture of soap and water, the flexible skin stretches into a sphere shape round like a ball , making a bubble!
You can see the flexible skin that forms a bubble by dipping a bubble wand into some bubble solution. See, I told you that you already have everything you need to make bubbles! That was quick! We are reading to bounce the bubbles in our gloved hand. The bubbles bounce!

Kids Expand child menu Expand. How to make homemade bubbles for kids to have a never-ending supply of bubble solution. When I wrote about making homemade bubble wands with the kids , I promised to share photos of them using their new bubble wands as well as the instructions for how to make homemade bubbles. Note: This post has been updated from the original with new photos and information. Add the dish soap and whisk to combine. This step is only if you have some patience or think to make the solution ahead of time.
Letting the homemade bubbles sit for a couple of hours or even overnight helps them work a bit better, but is not strictly necessary. Those each make the bubbles work just a tad better.
We usually simply have a big bowl or two of the bubble solution out and available to the kids. You can also hand individual mason jars with bubble solution to the kids.
Or re-use one of those no-spill bubble cups for your homemade bubbles. Check out The Artful Parent Amazon storefront for our favorite and recommended products, art supplies, and toys. Sometimes they blow bubbles themselves, sometimes they let the wind do the work, and sometimes they twirl around with bubble-laden wand in tow. How about you? Have you made your own bubble solution?
