If I put a glass of cocoa or milk in the microwave and get it out when it's hot, hold it in my hand and tap on the bottom of the glass (or mug) with a spoon - so with the spoon in the drink, not under the glass - the sounds it makes starts out as a really low "toc" but becomes higher with each tap. What is happening? It's not as if the glass becomes much hotter or colder in the first 10 seconds after I get it from the microwave.
