Fortunately it didn't have any antimatter in it...
because the next user carelessly emptied it into the air.
I taste terrible so they leave me alone.
The next user is delicious and is surrounded by cannibals.
I now am a blob of neutron matter with a conscience.
1 teaspoon of neutron matter falls on the next user's head.
I am a self-aware neutrino.
The next user simply stops existing, with every trace of them vanished. They will never reappear. No one will ever bring them back. They will nevet even come back in another form or incarnation.
Wow.
Well this is awkward.
I stop existing in a pararel universe, so I keep existing in this one.
The next user is totaly naked and shot in the head with a bullet travelling at MACH-5. This is real life, so no ressurection and present day, so no imortality technology.
