Because metal conducts heat faster than wood. The temperature of the water will be carried up to your hand much more efficiently by the metal spoon than a wooden spoon.
Metal conducts heat better than wood, so the metal spoon quickly absorbs the heat from the hot water, making it feel hotter to the touch compared to the wooden spoon, which does not conduct heat as efficiently.
Wood is an insulator. Think about it; when you put a wooden or plastic spoon in boiling water, does it burn your hand? No. This is because it slows the flow of heat from the water to your hand. I do not suggest trying the same thing with a metal spoon, which is a good conductor.
When a metal spoon is placed in water, the water exerts an upward buoyant force on the spoon due to the displacement of water. If the force of buoyancy is greater than the weight of the spoon, the spoon may bend due to the imbalance of forces acting on it. This effect is especially noticeable if the spoon is made of a soft or thin metal.
The spoon sticking out of a cup of hot water also gets hot because heat is transferred from the water to the metal spoon through conduction. The metal material of the spoon allows heat to flow easily, causing the temperature of the spoon to increase as it comes into contact with the hot water.
Conduction
Metal conducts heat better than wood, so the metal spoon quickly absorbs the heat from the hot water, making it feel hotter to the touch compared to the wooden spoon, which does not conduct heat as efficiently.
Metal conducts heat better than wood, so a metal spoon will absorb heat more quickly from the boiling water, making it hotter to the touch. On the other hand, wood is a poor conductor of heat, so a wooden spoon will not get as hot as quickly in the same boiling water.
As the metal spoon is a good conductor of heat and because heat travels from a hotter reigion to a colder reigion,the metal spoon will conduct heat away from the hot water and thus,the emty glass will not crack.
Metal is a good conductor of heat. Wood is not a good conductor of heat, although I wouldn't exactly call it an insulator of heat either. If you put a wooden spoon halfway into a pot of hot water, the dry part of the spoon will not get hot even though the wet half will be as hot as the water is, if you leave it in for a while. But if you heat up a wooden spoon and keep it dry, let's say by leaving it on a baking sheet and baking it in the oven along with some cookies, you may be able to grab the spoon and pick it up even though it's hot. There's no way you could do that with a metal spoon because you'd "feel" the heat more with metal. The heat would be conducted from the metal spoon to your skin, but a wooden spoon won't conduct much heat to you.
Metals have specific heats higher than wood.

'nothing, it's like putting a spoon in a hot soup' Wrong ^ As the metal spoon is a better conductor of heat than the air the hot water (or soup) and the spoon as a larger surface area with the air (or active sight) it transfers heat to the surrounding faster, thus cooling the hot liquid faster.
some water vapor released from boiling would condense on the cold spoon as water droplets.
A wooden spoon
When a metal spoon is placed in water, the water exerts an upward buoyant force on the spoon due to the displacement of water. If the force of buoyancy is greater than the weight of the spoon, the spoon may bend due to the imbalance of forces acting on it.

yes because it will rust
To effectively remove mold from a wooden spoon, mix equal parts water and white vinegar in a bowl. Soak the spoon in the mixture for at least 30 minutes. Scrub the spoon with a brush or sponge to remove the mold. Rinse the spoon thoroughly with water and dry it completely before using it again.
