When something hydrophobic (i.e. unable to absorb water) punctures the surface of a bubble, it subsides. A dry wooden spoon destabilizes the bubbles when they come into contact with its water-repelling surface. This makes the boiling water retreat.
Why does a wooden spoon not get hot in boiling water?
According to Michelle Dickinson, the author of “The Kitchen Science Cookbook,” wood is an insulator so it isn’t going to conduct heat or electricity. When you put a wooden spoon on top of a pot of boiling water, it stays cooler than the pot where it is resting.
Can you boil wooden spoon?
Wooden spoons are one of the most commonly-used kitchen utencils but did you know they hide a dirty secret? … In the story, Matt suggested soaking your wooden spoons in a cup of boiling water for around 20 minutes to help release oils and liquids that have been absorbed into the wood.
What will happen if you put a metal spoon in boiling water?
Metals are generally good conductors of heat. … The rapidly moving molecules in the boiling water bump the molecules in the metal spoon. This bumping transfers kinetic energy to the molecules that make up the spoon, causing them to vibrate faster.
Why are wooden spoons good when stirring hot foods?
Wooden spoons don’t quickly heat to scalding temperatures, chemically react with acidic foods, or scratch pots and bowls, as their metal counterparts do. They don’t melt or leach chemicals or strange tastes into hot foods as plastic does. A wooden spoon can be used to stir any dish in any type of vessel.
How do you sanitize wooden spoons?

Can boiling water melt metal?
The process, called superheating, can more than triple the boiling temperature of water – to over 350 C. This is sufficient to melt many metals such as bismuth (271.4 C), Cadmium (321 C), Lead (327 C), and Tin (232 C) as well as many of their alloys.
What happens when you leave a spoon in food?
The reason is the utensil will have some of the food on it, exposed to the air. That food residue will start to crust over almost immediately. Because it’s exposed to air it will see vastly more bacterial growth then what’s in the container and it will cross contaminate the entire product.
