Directing the Flow

Trying to think of an example of flow, I realized I've seen this for the last couple of weeks. Whenever I have a breadboard in my hands, I add an input to it, which is electricity (5 to 9 volts). The output depends on the type of circuit that I've been building: sometimes it makes noises, sometimes it lights up, sometimes nothing happens (mostly due to the fact that I connected something incorrectly), and sometimes I even burn LEDs.

It's really cool to know I have so much control on what the output or result will be depending on some insignificant thing, such as if I connected a resistor in the right line of the breadboard, or if my battery still has charge left.

Thinking in a more abstract way, we could see an example of direction of flow in real life almost anywhere we look. For instance, imagine that we are throwing a party. If we advertise its gonna be fun and that no alcohol is permitted, the party will probably lack a nice number of attendees. On the other hand, if we advertise there's gonna be free alcohol all night long, it'll probably be a party really difficult to forget.

Another example would be restroom signs. While the restrooms are occupied, switch the signs, sit down nearby, and watch what happens when people start getting confused because those coming out are not the same sex.

The flow is affected by adding an input, and the outcome will depend on this.
