Bimetallic Teaspoon

 Novelty cutlery to leave lying around
  (+6)

Simply put, a teaspoon the handle of which is made out of a bimetallic strip. In the cutlery drawer it looks like a normal teaspoon, but immerse it in hot tea and the handle goes all curvy. No practical purpose. Not to be supplied to Uri Geller.

Chill and bend. Let it heat back up, and it moves back to its original form. [Amos Kito, Sep 30 2002, last modified Oct 05 2004]

       Terrible idea. It'll never work. I can't imagine what inspired you to write such rubbish.

       would it be better (or worse) to start with a cold curvy spoon that straightens out in your hot drink?

       Yeah, but po, what would you call it?

       My mother always answered that they were spooning in bed.

       There's nickel-titanium wire [link] that re-shapes with heat. You can customize its shape in a low flame.
Your spoon can be straight in hot water, and coil up to hang on a chain as a pendant when cold.

       Is this not the basis of a very simple, very slow, automatic drink-stirrer. As it heats up, it bends and moves the drink around one way. As it starts to cool, it unbends and moves the drink around the other way.   

       Of course, to make this in any way effective would require a very sensitive bimetallic strip, which would mean it would probably be next to impossible to place in your cup.

       Topsy-turvey teaspoon?
