Reproduction:
1. In the water deep enough, place 3*3 soul sand
2. Aim the trident high enough behind a center of soul sand
3. Throw it

4. Aim the trident just like before, just without soul sand

5. Throw it again

If you still don't understand what I mean, watch the video below

Note: In the video, I already thrown the first trident at the target practice for accuracy
