"What's so bad about being drunk?"
"You ask a glass of water."
I saw a show on worm holes and time travel a while back. I think they said, hypothetically, that it would take the 5%
of the mass of Jupiter to create a one meter diameter "rip" that would last for one second.
Just big enough for one person to jump through it.
So, the amount of energy required is phenomenal, and then, I'd bet you'd need to protect everything around it,
including the cargo...
Hopefully they brought their towels!
...and good luck "aiming" it.
