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. WHAT HAPPENED DURING THE BUBBLE TRICKS Bubble Trick #1 Response: Can you stick your finger through the bubble? Try it again with other pointed objects, just make sure anything you touch to the bubble is wet. Poke the scissors through the wall of your bubble.
Now dip the pointed end of your scissors (or any pointy object) into the container of bubble solution.Slowly pull the straw all the way out of the bubble. Touch the straw to the lid and blow a bubble on the lid. Dip your straw into the bubble solution container so that it is wet halfway up the straw.Set the lid on the table so that the part with the lip is facing up.Dip the bubble blower into the bubble solution and slowly blow a bubble through it until the bubble comes loose from the wand.Twist the ends together to make a handle. Fold the other pipe cleaner in half and loop it around one side of the square.
Wrap the ends around the sides of the square to hold it together. 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.Īfter 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? Bubble Trick #1: Soap needs to be mixed with the water to make bubbles that can float through the air. 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. The force of surface tension also creates bubbles. 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 water molecules still stuck to each other and nothing spilled! 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. 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. The molecules on the very top of the water stick together very closely to make a force called surface tension. The molecules are attracted to each other and stick together. Water is made up of lots of tiny molecules.
