Aerosol cans are a very handy painting tool. The paint applied in this way does not have the characteristic streaks or irregularities of the brush, which are left by the nap of the roller. In this way, you can apply not only paint, but also varnish. The small can is comfortable to hold and easy to transport, while the aerosol will help paint hard-to-reach parts that are difficult to reach with a brush. In short, the spray can is very easy to use. But he has one significant drawback - disposable packaging. There is not so much paint in a cylinder, and to paint a large part, you will need more than one cylinder. It turns out that you have to pay for packaging over and over again, and the consumption of the paint itself turns out to be very small. How can this situation be corrected? There are two options. First, an airbrush can become an alternative to a spray can, but the cost of such a device starts at 800 rubles, and you still need to get used to using it. And the second option is to make the can... reusable. How this can be done, showed the author of the YouTube channel The labOtomy.

What is required for work
So what's the point of the rework? We need to find a way to fill a sealed container with paint and pump air into it to create the necessary pressure. Moreover, it is important that no special tool is required for this procedure.
To make a reusable aerosol can, you only need one additional part, which you can easily find - a bicycle nipple.
It remains only to assemble all the parts of the device into one whole.
Converting a disposable cartridge to a reusable one
To install the nipple, you need to choose a place at the top of the can.
Just glue is not enough to connect the parts; you need to additionally strengthen this place with soldering. For this procedure, you will need a can of gas and a special nozzle - a gun, which gives a constant, narrowly directed flame. In general, such a nozzle will come in handy in many household chores and will be completely irreplaceable when making live fire. So if you have not yet acquired this device, it makes sense to do it. Such a gun costs about 200 rubles, and you can buy it at any hardware store.
The nipple opening in the bottle is very small, so it will be convenient to fill in paint through a syringe without a needle. The size of the under-needle cone is just right for this task. But there is a nuance: the cylinder cannot be filled completely, there must be room for air in it.
And now there is only one small step left to make the cylinder operational - you need to create the necessary pressure in it by pumping air.
You can prepare several cans this way if you want to use paint to create multi-colored images.
How to make an airbrush from scrap materials
It is very convenient to use aerosol for creativity and fine work. And if necessary, you can build the airbrush yourself, using a ballpoint pen. How to do this is clearly shown in this small video:
