== Directionality ==
Directionality is a property that is unique to Redstone and Lapis Blocks, where they prefer to output power in the same direction that they received it. 

For this example I'll be using Redstone Blocks.

Below is an example setup to demonstrate the effects of directionality.<br>

There are two inputs - one coming in from the back, and one coming in from the right.

Ideally, you would want to merge the outputs of the power banks and split it evenly to the two power cells.

But here’s what happens if we give power to the bank on the left:<br>

As you can see, the bottom power cell receives nothing. 

And if we only power the bank on the right:<br>

We see that both of the power cells were filled.

The reason it powered both, as you might have been able to observe, 
is that the path from the bank to either power cell was not a straight line. 

The Redstone Block was not able to send the power to the side opposite its input, so it split evenly to the other directions. 

Situations like this are really important to be aware of in almost any wiring project you do that have multiple input/output locations.

Luckily, the solution to this problem can often be fixed by simply inputting power through opposite sides of the Redstone Block, like so:<br>
