You won't actually blow any bubbles, but you will learn the science that makes a bubble! Put the first glass of water in the center of the pie plate. Slowly pour some water from the second glass into the first glass until it is very full and the water forms a dome above the rim of the first glass.
Set the glass with less water aside. Carefully stick your finger straight down through the dome of the water in the full glass and watch what happens.
Now put a small drop of dish soap on the tip of your finger and do the exact same thing - stick the finger with soap on it straight down through the dome of water. This time what happens? Water is made up of lots of tiny molecules. The molecules are attracted to each other and stick together. The molecules on the very top of the water stick together very closely to make a force called surface tension.
Surface tension is what caused the water to rise up above the rim of the glass in the experiment - the water molecules stuck together to make a dome instead of spilling over the side. Why didn't the dome break when you stuck your finger through it? 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. I just love how making bubbles is so easy, and you can create unique bubble makers with things found around the house.
Bubble snakes can easily be made with a water bottle, washcloth, rubber band and soap! Cut off the very bottom of a water bottle, then cover with a washcloth and secure with a rubber band. Then just dip into some bubble solution and blow! You will see an amazing bubble snake emerge! Check out TheBensonStreet. Source: ProjectsForPreschoolers. All you need to do is a take a clean water bottle and poke a small hole in the bottle.
This is where you will be blowing air into the bottle. Then dip the opening at the top into bubble solution and start blowing! You need to visit ProjectsForPreschoolers. Source: OneCharmingParty. This is probably one of the largest bubbles you can make, and you just need a kiddie pool and hula hoop! Add bubble solution to the baby pool and let it sit overnight.
Then lay the hula hoop in the pool and have someone stand inside the hoop. Source: Familycious. The washer will go on the long piece of rope to provide you with some weight. You will seriously be amazed and how big these bubbles will be! Advertisement - Continue Reading Below. Best Overall Bubble Machine. Gazillion walmart. Blows a LOT of bubbles.
