FAQ:
Does it work on Bedrock Edition?
No - The boat hitbox is different, causing it to burn in the lava when dispensed.
Why doesn't it work on Donutsmp?
They have a plugin that stops boat collision to reduce lag, which breaks the trap. (It can still be done with a slightly different setup - planning to make a video on that at some point)
