I dunno about your house but the tap water (or instant 190F water, which is what I really use) is fairly consistent. Maybe you would need to add a few secs in the winter. But people get into real superheating trouble (the kind with water flying everywhere) when they heat the water way past 212, not just a few degrees. If left without a nucleation site, the water may get up to 220, 230 , whatever without visibly boiling and then instantly flash to steam as soon as it is disturbed. So the trick is to heat the water only to 212 or even below. You gotta use common sense and not heat a single cup of water for 10 mins. Common sense appears to be in short supply in our society - not only is it not taught in schools but many times the exact opposite.

I nuked a Pyrex 2 cup measure for 3 minutes for years, then one day it exploded. I never heated for a second past the boiling point.

I started with cold water because I use a filter pitcher, not straight tap water.


Having "something" in the cup is not as easy as it seems. If the "something" is metallic you may get sparks. Otherwise (glass marbles) you have something that can spill out and splash, that you have to keep track of, etc. Much easier to just not overheat the water in the 1st place.

I use a wooden chopstick or small wooden spreader. I don't want chemical leakage from a plastic spoon or such. For my money, since the chance of severe burns and even maiming is so high if one miscalculates, it just seems smarter to a) use a teapot and b) put a wooden utensil (you could use ice cream pop type craft sticks) standing in the cup. We're not talking about a huge additional effort here, hardly worthy of lengthy debate. :-)
