Candle help (with pic) am out of ideas!

[VeryFoolishFay]

I bought these candlesticks in Crate and Barrel, on holiday in the States 27 years ago. They weren't expensive but I am very attached to them.

You fill them with water and the candle floats at the same level, obviously getting shorter as it burns.

Took my eye off them at Christmas, they burned down too low and now have wax stubs wedged in them.

Any ideas how I remove them? To be honest, the glass seems quite fragile so it needs to be a gentle approach!

Hairdryer round the edge to melt them a wee bit so they slide out?

Hot water but not boiling and a pipe cleaner if you have one around.

Consistent but gentle heat to the outside, and something long and pointy, like a knitting needle. Heat and wiggle.
