Patterns involving sparks

[Quantum-mechanics]

Thread for discuss the sparks, sparkers and spark eaters.
This is a failed eater, it will created a big spark, the spark can eat glider:

Must find a pattern for created beehive with that big spark.

Can eat glider...

I experimentally changed the title of this thread to "Patterns involving sparks". If that wasn't the intended meaning, feel free to change it again.

Just a note about the glider-eating ability of the dying sparks at the end of the reaction: this is an extremely common feature of conduits. If a reaction like this was not able to suppress an incoming glider at some point in its evolution, that might actually be slightly more surprising and unusual than the fact that it can suppress an incoming glider.

So you'll definitely see cases where people note that an oscillator or conduit's dying sparks can reflect a glider, but it's usually not necessary to mention that a glider can be absorbed.

Can call it XWSS eater, but it cannot eat LWSS.

It's worth noting that the block in BRx46B can be placed in one of two different locations:

The placement on the right has one extra lane of clearance.
