Using this method, you can "seal" droplets of water on the surface of the material.
For this we need: a container with a spray and an aerosol can with paint.
The technology is simple. Pour water into a container with a spray. Spray water on the surface of the material. Spraying should be done so that drops of water fall from above and in one direction.
Now, from a distance of 50 cm, you need to spray paint. No need to direct the jet to the surface. It is necessary that a cloud of paint forms, and it under its weight dropped to the surface.
Now you need to let the paint dry. It is advisable to do this in sunny calm weather. After drying, a coat of colorless varnish can be applied.
The master experimented with different materials and this effect is best manifested on acrylic, glass, i.e. on those surfaces that do not absorb moisture, and on which droplets do not slide.
