Minecraft wiki entry for Bell, associated text: In Bedrock Edition, bells deflect any projectile that does not disappear when hitting a surface (arrows or tridents).
In Bedrock Edition, when holding down right click while looking at a bell and holding an item with a right click action, the bell rings once and then the player uses the item.[2]
If a villager tries to give another villager food near a bell, there is a chance it might hit the bell with the food and cause all the villagers to run, thrower included.‌[Bedrock Edition only]
In Java Edition, if a bell is used with a button, there is a chance for the bell to play the ringing sound in reverse.
