The average human is made of about seven billion billion billion (7 followed by 27 zeros) atoms. Of this, almost 2/3 is hydrogen, 1/4 is oxygen, and about 1/10 is carbon. These three atoms add up to 99% of the total!
An atom is just a nucleus made up of protons and neutrons, which has electrons orbiting around it. An atom is about 99.9999999999996% empty space, so that means we ourselves are 99.9999999999996% empty space, just like outer space, our bodies are just big empty spaces with a bunch of small spherical objects orbiting around other spherical objects, made up of the same material as the stars in space.
For this challenge, the artists are using empty space to create their art.
Each artist uses a plexiglass panels coated in black paint and a variety of tools to etch their design. Acrylic paint was available to use to add colour to their panel. These pieces are best viewed when hung in a window, allowing the starlight to shine through the design, bringing them to life. Check out the final pieces below!
