Scientific description
You were able to create this beautiful picture thanks to the interaction of two liquids with different viscosities! The red liquid (PEG-400) 
is highly viscous and consists of large molecules bound together. Under the plastic disk, it spreads out in a circle.
The colored water (blue and burgundy) from the bottles, however, has a lower viscosity. It is fluid and consists of small molecules 
bound loosely to each other. The colored water spreads in a circle, then breaks off in different directions, forming a snowflake inside the red liquid .
Under the plastic disk, the molecules of the liquids behave like cars in a traffic jam. The molecules of the colored water from the bottles are cars, and the molecules of the red viscous liquid from the syringe 
are huge, lumbering trucks. The trucks create a traffic jam around the cars and do not allow them to pass. With the help of the bottle nozzle, we create pressure on the colored water, and it pushes the car-molecules towards the truck-molecules. That’s why as soon as there is a space between the trucks, the cars immediately fill it and continue to make their way further, driven on by the impatient cars behind them.
