Bottle Your Xp is a minimalistic configurable mod which allows the creation of experience bottles (bottles o' enchanting) from your own gathered xp by sneak/crouch + right-clicking an empty bottle. This can optionally (set in the config) hurt the player because the procedure might not be entirely painless.
All available config options:
Show Spoiler
damageOnCreation default true
If enabled, damages the user whenever they create an experience bottle.
halfHeartDamageAmount default 1, min 1, max 20
The amount of damage the user takes times half a heart when creating an experience bottle.
rawXpConsumedOnCreation default 10, min 0, max 100
The amount of raw xp it takes to produce an experience bottle. Be careful when setting this too low, as it may enable xp duplication.
The effect in action:
Show Spoiler
