Ten kinds of scientific liquid tricks that can be made with ordinary liquid

Various kinds of casually using in usual life such as water, kitchen detergent, cooking oil etc.liquidIt has an interesting characteristic that I do not know unexpectedly. A movie summarizing interesting movements and properties of such a liquid "10 Amazing Science Tricks Using Liquid!"Has been released.

10 Amazing Science Tricks Using Liquid! - YouTube


◆ 01: Slow motion ball
Prepare to prepare honey, iron balls, and a transparent round case that is one size larger than the iron ball.


Put the iron ball in the case, and put the honey on the top.


Close the case with honey until about two-thirds of the case ......


I roll from the top of the slope.


I thought whether it would roll as it is "Gurunburu!", And the case where I get off the slope with a netted move and an iron ball. It seems that honey is resisting and braking the force rolling the case.


I rolled slowly to the bottom of the table as it was.


◆ 02: Turn on fire with water
This time we use water to fire the paper. We prepare 2 white paper and black pen, rounded PET bottle and water.


Fold the paper ......


I paint the surface black with a pen.


Put water in a PET bottle and take it on paper under sunlight ......


The PET bottle with the water played the role of the lens, the light concentrated on one point. It is the same principle that we conducted an experiment using a magnifying glass in science.


I put another piece of paper on the fire-laden paper and it burned violently at a stretch.


◆ 03: Tear-free bag
Pencil, bag with zipper, and prepared water.


Pour water in the bag, slowly bend the sharp pointed pencil. I feel that the bag will tear and water will leak, but it does not seem to leak even a single drop of water.


Even if I pierce five pencils, there is no problem at all. This is the point that I stabbed the pointed object slowly and without changing its position. By stabbing slowly, the material of the bag deformed so as to stick to the pencil, and high confidentiality was maintained.


◆ 04: Stack liquids
What you prepare for a wonderful experiment of "loading liquids" is a vertically long transparent container and kitchen detergent, vegetable oil, dark corn syrup, isopropyl alcohol (alcohol for disinfection), and water.


I will pour these liquids in order into the bottle, but the important order is to pour in that order. First insert dark corn syrup ......


Next, I added detergent for kitchen. In both cases, I put liquid that I thought was a tramp first.


Next, tilt the bottle and inject water. For easy understanding, water is thinly colored.


Injected vegetable oil while tilting the bottle.


Lastly injected colored alcohol.


Then, five kinds of liquids did not intermingle and stacked beautifully. This was based on the specific gravity of the liquid and the difficulty of mixing.


◆ 05: Bottle to disappear
An experiment in which a glass container and glycerin, a thin glass bottle are used to make the bottle invisible.


Pour glycerin into a glass container ...


Pour glycerin also into the thinner glass bottle.


In this state, when inserting the bottle in the container and looking through the other side, the bottle that was supposed to be in the container became completely invisible.


When water is put in the glass bottle, it is in this state as if it is full. It was a trick using the refractive index of light.


◆ 06: Dancing liquid
I will dance like a liquid alive this time. I use cornstarch powder and speakers, plastic bags and water.


Put water in cornstarch powder and mix it to make a Trotoro liquid.


Place a plastic bag on top of the speaker and pour the cornstarch liquid from the top with a trolley ......


When we heard the sound from the speaker, the white liquid began to move in a squiggly manner.


It looked like it was as if some creatures were flying around.


In addition, by placing a paint on the speaker and giving out a sound, you can also see the artistic scenery in the following article.

◆ 07: Water not mixed
In the experiment of "04" I saw how different kinds of liquid did not mix, but this time a mysterious experiment that the same water does not mix. We prepare hot water and water, two glasses, one plastic plate, and two coloring pigments for coloring.


Let's start by putting cold water in two glasses.


Color with coloring matter to make it easy to understand the mixing condition.


Cover one of the glasses with a plastic plate ......


It turned over and fitted snugly on top of the other glass.


When slowly pulling out the plate, the upper and lower water gradually starts to mix ......


Soon both of the water became mixed. With this method water mixes.


Next time, I will put hot water in one glass and try the same experiment.


Colored in the same way, overlay both glasses. At this time, it is a point to overlay hot water glass.


And even if you slowly pull out the board ......


The upper and lower water is not mixed. This is due to the difference in temperature due to the difference in specific gravity and concentration, it is born an interesting state "hot water floats on water".


◆ 08: Leiden Frost effect
It is easy to predict that if you put water in a heated hot pot, it will be boiling as "Juu!", But it seems that it looks a bit different by the heat of the pot. We prepare a pot and water, and a stove to heat the pot.


Even if you put water in a cold pot, nothing will happen and only water will build in. This was natural.


Next, when I poured water into an ordinary hot pot, it sounded "juicy" vigorously and boiled while raising steam. This is a sight that you can easily imagine.


However, when I put water in a hot pot, it showed the movement that the water would be played in the pot and slid the surface of the pot.


Even if you pour a lot of water, it does not change. I show the movement that is floating in the air.


When I shook the pot, the water began to rotate around the bottom of the pot round. this isLeiden Frost effectIt shows the effect called. When a liquid is dropped on the surface of a solid which is at a temperature much higher than the boiling point of the liquid, a part of the liquid boils in a moment and the vapor floats the liquid by creating an air layer between the liquid and the solid, It is a condition where boiling does not occur easily by inhibiting the transmission of temperature.


◆ 09: Object to flip
Pour water into the glass and see the object reversed when you look through the other side. Only prepare paper and pen, round glass and water.


When pouring water on the glass, the letters "won" written on the paper stood on the other side ... ...


It changed to "now".


Such a pattern of mysterious shapes ... .... ·


Change to left arrow.


Funny formulas such as "800 + 081 = 188" are also ...


By inverting it, I was born to be the correct one "008 + 180 = 188".


◆ 10: Reverse regeneration liquid
And this experiment makes me feel the fun of the liquid best. Prepare two large and small glass containers and small glasses, corn syrup, 3 pipettes for taking liquids, 3 colorants and 4 large clips.


First, put corn syrup in two glass containers and place a thin container in a large container.


Then, attach a clip to the larger container so that the thin container will be the center, and fix it. Leave as it is for a while and wait until all air bubbles get out.


Put corn syrup in a small glass and color it into three colors with coloring.


Suck up the corn syrup colored with a pipette ......


Put it in a container. The place to put in the transparent corn syrup in the middle of large and small containers.


And when you rotate the thinner container at the center ... ...


The three inside colors changed like a whirlpool. This is because the transparent corn syrup was pulled by the rotation of the container.


And from here it is the real point. Rotating the inner container in the opposite direction as before ... ...


The three colors that had been swirling up until a while returned to their original state almost as though they had played back the image in reverse. It was a moment when the voice leaked out as "oops" as it was a liquid without shape, showing an orderly movement.
