Time Machine
A scientist was convinced that his recent Time Machine invention could also double as a replicator.
To prove this, he sent his pet duck 1 minute and 2 minutes into the future simultaneously.
After a minute, the first duck appeared unharmed.
The second duck materialized and both ducks were instantly annihilated.
The appearance of the second duck had created a pair of ducks.
