Here you can see the water simulation I developed in p5js. Here you have access to one of the random types of interaction with this liquid

GRAVITY:
This type of interaction allows you to change the direction and strength of gravity by tapping the screen.
Press the F key to reset the position of all fluid particles

SPAWN:
This type of interaction allows you to create new liquid drops.
Press the F key to spawn the maximum number of particles at once (500 on phone, 2000 on PC).
Click on SPACE to remove all drops of liquid.
Press ENTER to increase the maximum number of particles to 10000.

A pixelation shader can also be applied on top.
