Hi, I have been building and experimenting with command blocks in a world( with cheats, switched between game mode a lot). I enchanted a trident with the following enchantments:

1.impaling 5 

2.channeling

3.loyaly 3

4. unbreaking 3 

5.mending

it is also named( taser), and I ran the following command in a repeat(purple) command block: /execute @e [type=thrown_tridend](maybe a ~ ~ ~here) summon lightning_bolt ~+1 ~+1 ~+1 

I tried throwing it around and no problem, but when I got struck by lightning and died(the trident hadn't come back yet),I respawned and went back to the location in 2 minutes but the trident was nowhere to be found. I looked for it for another 3 mins but still no trident.

I tried this 2 more times but the trident  already came back and is dropped on the ground. So I couldn't get a video. Can you please try it yourself?

steps:

1.trident 

2.enchant with above enchantments, then name it taser with no Caps

3.run command block on repeat with Redstone with above command

3.get to 1 and a half hearts

4. throw at floor 3 blocks in front

5.die( to lightning)

6. gone

Thanks! PS this was in 1.14 something, but I couldn't find the version, sorry!
