Yes, if you get something extremely cold and put it on your forehead, it's believed you will, indeed, get a brain freeze.
The liquid in thermometers contracts when placed in something cold (and expands when placed in something hot.)
The word polar tends to mean something cold. Example:Polar Bear.
Changing a liquid to gas is called evaporation.
Evaporation occur at any temperature but a high temperature favors evaporation.
No. Heat can only be transferred to a cold spoon, not the other way round (as there is no heat in a cold spoon to transfer). A simple example is when a cold teaspoon is used to stir a hot cup of tea. When the spoon is withdrawn, it is hot.
Normally, any spoon you put in ice cream(wooden or metal) becomes cold.
You need something really cold. You or anything from inside your house will be too warm and the snowflake will melt as soon as it touches. If the weather outside is cold enough, you can leave something, like a spoon, outside until it cools off. Then you can use it to catch a snowflake. If the weather is too warm (the snow is not sticking to the ground, but melting), put the spoon in your freezer for a hour or so.
A higher rate of evaporation has hot water.

A cold spoon will extract heat from the soup, a spoon that is warmer than the soup will transfer heat to it.
If stuck open the car will run cold. If stuck closed the car will run hot.
Evaporation is when a liquid turns into a gas. It can happen when liquids are cold or when they are warm. It happens more often with warmer liquids.
Evaporation cools it.
An absinthe spoon is used to sweeten the absinthe. The spoon is placed on the rim of a glass and a sugar cube is placed in it. Ice cold water is dripped onto the ice cube and into the glass.
