How exactly does cleaning 4kg powder soap function? Long molecules with a head and a tail are used to create soaps and 4kg powder soap.
This kind of molecule is called a surfactant, and an example of one is shown in the figure below.
The molecule's hydrophilic (water-loving) head is balanced by its lipophilic (oil-loving) tail (hydrophobic).
The molecules' tails are attracted to the grease on the clothes, while the molecules' heads remain in the water.
The grease on the surface is dislodged due to the strong attractive forces between the head groups and the water.

The force of surface tension is what prevents a puddle from spreading once it has formed.
4kg powder soap molecules that act as surfactants disperse these forces, causing water to act more like water.
A thin layer of water is sandwiched between two layers of soap molecules to create bubbles and soap films.
These ingredients, when combined, produce enormous bubbles: All you need is 1 liter of water (preferably distilled, but tap water will do), 15 milliliters of high-quality dishwashing liquid (we used Fairy), and 10 milliliters of glycerol/glycerine (found in the baking aisle of your local grocery store).
You can now perform our four experiments using your homemade bubble solution.

To demonstrate, blow a huge bubble and see if you can stick your fingers inside it.
A moist hand allows for safe contact with the bubble, even reaching within.
Even as it bursts, a soap bubble is just 1/500,000th of a centimeter thick! Make a big string hoop, about 1 m in diameter, and tie four little loops at the corners to use as handles for Experiment 3.
Put it in the soapy water, then pull the two handles apart to create a huge soapy sheet.
If you shake the film from one end, you can see the wave propagate across it.
Procedure 4 Now try your hand at making a bubble dome according to our helpful diagram.
Pour some bubble solution onto a tray or the kitchen counter.
Create a massive bubble using a straw.
Create a tiny bubble by inserting the straw into the larger one and blowing air through it.

A pin may float on the surface of water due to surface tension, and pond skaters and other insects can walk on it.
Simply floating a pin in a basin of water will show you this for yourself.
Add a single drop of dish soap and watch the pin's reaction with caution.
The 4kg powder soap molecules disrupt the forces that hold the water together, thus the object should sink instantly.
Since there is nothing holding the pin in place, it will eventually fall to the floor.
The Button Balance is a tool for gauging the tension of a surface.
Make a button balance, like the one used by the well-known home experimentalist of the nineteenth century, Agnes Pockels, to measure surface tension.
A lolly stick, nylon thread, button, plasticine, graph paper, card, and a container for the liquid to be tested are required.

Raise the bottle or jar slowly until the bottom of the button side makes contact with the soil (the rim should be facing down).
You should be able to see that the lever is angled in such a way that the end is below the water.
Either by adding very little weight to the counterbalance pan or by moving the pan along very slowly, you will be able to raise the button such that it is visible above the surface of the liquid.
You could try replacing the button on the liquid surface in order to confirm that the weight, and not the process of dumping the weight into the counterbalance pan, was the cause of the button falling off.
This will ensure that the weight, and not the process of dumping the weight into the counterbalance pan, was the cause (or sliding the counterbalance).
