Any idea how I can get these two unstuck?

[Happytodayhappytomorrow]

I’ve tried soaking them in hot water but to no avail.

TIA

DW40?

Or even WD40 😁

Bottom bowl in hot water cold water with ide cubes in top bowl

Freeze them.

Stand them in hot water (not boiling) and put cold water in the top one. Worked for me this week

Can you submerge the whole bottom one in a sink of hot water and at the same time fill the top one with ice cold water?

Cold water in the top one, it should contract, put the bottom one in hot water to expand it. And washing up liquid in between.
I have no idea if this will work, but it sounds vaguely possible.

X-post,

Cross posted with everyone!

At least there is a consensus

Try and squeeze a straw between them and see if you can blow a bit of air in.
If they’ve been stacked with any residual water on/in them then that will have got them stuck and the air should help to loosen them.

Thank you all
Trying it now……

Yippee!! Thank you all

I only clicked on this thread to see if anyone had suggested sex lube and a fish slice yet
