You could make it a primary school problem. Measuring melting ice in a cup is kitchen physics, cooking is kitchen chemistry.
Get a globe if the world.
Trace Antartica.
Photocopy tracing.
Cut out the photocopies.
Blue tack them to the globe.
Count the number of Antarticas that now cover the globe.
Take the thickness of the ice in Antartica (averages ~ mile)
Divide thickness by number of Antarticas to cover the globe.
You have an approximation on how much the worlds waters could rise.
I prefer the martini glass exercise. Take a shot glass, fill it with vodka, and pour it into a martini glass. Mark the level with a marker. Fill shot glass, pour, mark again. Fill, pour, mark again. Notice the lines get closer as more shots are poured in. This is what will happen when the icepack melts. Now drink the vodka.

EDIT:
It has been explained by half a dozen people already, all replying to you directly, that currently we are observing the melting of the Arctic's floating ice, and not the ice covering the Antarctic land.Originally Posted by Frag
It was also explained exhaustively why the difference is crucial.
Come on, now that we even proved there is plenty of solidified water to raise the sea level way above your threshold, are we going to just repeat the whole discussion for the sake of it?
@drone, ACIN
Look, my remark was a reply to Frag’s insistence that calculating mathematically that the sea level could rise by 40m is impossible.
drone: But it's not an elementary school problem.
ACIN: Pssshhhh, I was calculating this kind of stuff in 5th grade.
Thus I really don’t see where’s the cause for irony
We were taught about buoyancy and how to calculate its force (hence also establish displaced volumes) precisely in the 5th grade, which inaugurated our first year of physics classes.
We were taught about density in the 6th grade.
Normal kids in a normal school in a normal 250.000 people town in a normal east-European country.
Now I will give you that perhaps that is middle school, not elementary, I am always fuzzy when it comes to your system – we go through general school (1st to 8th) and lyceum (9th to 12th) here, so we don’t really make a distinction.
Oh well, I guess we really needed the off-topic, you meanies ganging up on poor old Nowake![]()

I did read the posts in question in that kid's thread and I found your sarcasm towards Sarmatian's comment - that is, your switching of his name upon quoting him - brilliant and a great pity that no one else remarked upon it but me - or perhaps they did and did not comment on it as well.
So I find it hard to reconcile your usually biting humour with this awful incapacity or refusal to understand the facts above.
But the water doesn't rise all that much since 1981, surely we dutchies must have noticed it if it did. Attenwhatshisnam is full off it, should stick to filming polar bears in Amsterdam's zoo. Nothing to be absolutely terrified about, it ain't happening
