Glider destruction (B3/S23 only!)

So, everybody's heard about glider construction. What about glider
destruction?
Like, what's the smallest number of gliders it takes to destroy an object?
For clarification:
- You only need to find one solution.
- It can be any pattern! Spaceship (don't post solutions for gliders—they're trivial), oscillator, rake, you name it!
Here's what I have so far. Feel free to post more!
Code: Select all
#C ### THE HALL OF DESTRUCTION ###
x = 27, y = 27, rule = B3/S23

Welcome to the forums! Unfortunately this topic does not warrant a dedicated thread. We have
a little script and another program named
Seeds of Destruction for the purpose. And you can come up with a cleanup easily just by moving gliders around manually and seeing what they do.
Glider destructions are commonplace in
glider synthesis, sure, but there are often additional constraints for not destroying other objects in the close proximity. Also there are lucky cases where you can remove a number of objects at once. These make a precompiled destruction database more unnecessary.
Finally, please use code tag (the fifth button labelled </>) instead of a viewer tag without commands for simple patterns, because the former takes up less space.

This idea does come up every now and then. Apologies for the uncertain welcome for this idea, but it does go better in the Sandbox -- a few other similar threads have been started over the years, so I've moved these posts to one of them. Here's a link to
another similar thread.
To anyone who might be worried, the apparent necropost is my fault, not squareroot12621's --!

This
xs16_6413kkozx56-producing reaction is very messy. How well can you tame it with gliders? As usual, the fewer the better.
Code: Select all
#C [[ STOP 147 ]]
x = 32, y = 25, rule = B3/S23
22b2o$22b2o3$17bo$16bobo$17bobo$18bo6$30bo$29bobo$29bobo$25b2o3bo$26b
2o$25bo3$bo$obo$obo$bo!
Similarly, this for
xs16_69m88a6zw23
Code: Select all
x = 68, y = 21, rule = B3/S23
16bo$15bo$15b3o2$20bo$19b2o$19bobo10$b2o$obo$2bo62b2o$65bobo$65bo!
And
xs16_69m88cz6221
Code: Select all
x = 29, y = 25, rule = B3/S23

You know, glider destruction can be very powerful sometimes, like in the following synthesis:
Code: Select all
#C [[ GRID MAXGRIDSIZE 14 THEME Catagolue ]]
#CSYNTH xs16_6413ia4z6421 costs 9 gliders (true).
#CLL state-numbering golly
x = 120, y = 75, rule = B3/S23
