Main Question or Discussion Point

I came up with something to think about while freezing in my room...

How can one measure the temperature in a room withought traditional termometer.

Alternative formulation of the question - is it posible to construct a termometer that would measure such temperatures as are measured in a room: that would be sensative enought?

Or maybe there is some indicator of temperature? (the temperature is higher than 0 degrees C, so freezing water is not an option).

I came up with only one way - open the fridge and count the interval lenghts with which it will turn on. Anyway there is an assumption here that the frige is working with an inbuild termometer, and not just turning on/off in a predetermined time...

Can some one come up with some easier way? I can't measure the initial temperature as I say, because there are no reference temperature indacators in the room (I could open the windows and wait till the water freezes (so it will be 0) and then wait till the the temperature reaches the temperature outside (which I can look up on the net) and then use the freezer not the fridge to measure the temperature ... but I will freeze myself then ...

I'm interested is it posible to construct such a device with some kind of liquid whose properties of expansion are known (i dont have spirit, onlu water) or maybe with some kind of hard materials...

Waiting for a good "physical reasoning" ...

P. S. my sences and intuition tell me that it is about 10 - 12 degrees here...
