Fill with mercury. The rocks will float to the top then you can just pick them up.

And when it's time to get the mercury out:
How is this practical or safe?
when he claimed it was?
It is practical as rocks should float in mercury and it is safe if you use elemental mercury and don't eat it.
It isn't environmentally fantastic and you would want to remove it with a vacuum trap, which does make it a less than ideal option compared to a shopvac.
Suck hard. If you need help ask your momma
Op should have just said "friend". Now he's downvoting all the mama jokes
If the long spoon, backscratcher, or shop vac doesn't get it done, I'll give this a try. Thanks.
Your best bet is probably to vibrate them out.
Now given this is your moms house, I am unable to politely suggest what household items would be useful.
Blue tack and a stick? Like stick the rocks to it then pull out?
It is either a powerful vacuum or a blower depending on the size of the gravel.
a powerful vacuum
A shop vac, maybe with a narrow extender.
If OP is in the US -- which I assume he is, from the inch measurement -- I'd bet that he can probably rent one at a large hardware store, like Home Depot, if he doesn't have any use for one outside of this.

eh, they could live as well in Liberia or Myanmar
I’ve never seen a shot vac extension that would fit into a 2” pipe

Not specifically recommending this one, but this has a crevice tool and adapters for various diameter shop vac hoses.
Curious...why do you need to remove the rocks from the pipe?
She can't slide the clothesline into the hole to set it up.
Maybe the clothesline doesn't go far enough I to the ground hole to stand up straight.
Air compressor with a skinny long nozzle.
This was also my thought. Wear eye protection!
Long spoons. Or a backscratcher would work.
I did not think of a long spoon. I'll give that a try. Thanks.
A coiled wire screwed to the end of the stick (like a spring). Jam over the rock and pull up.
Or put silicone on tip of stick, glue to rock, cut stick, apply more silicone and repeat until empty.

Something like this might work. They are kind of expensive, and some are better made than others, but they come in handy and maybe you could borrow one from somebody. A landscaping company might have something like this too that they use to get fruit off of trees, or maybe a fire department has something like it. Possibly a pond and aquarium store has some equipment that could work since they need nets and tools for plants and rocks, or tools used for feeding aquarium animals and fish. There are some home improvement stores that let you borrow tools or rent tools, shop vacs, long handled gutter cleaners or painting tools etc.
