Actually the same thing can happen from boiling water normally although once it is actually boiling it will not occur. It would have to be just before it was ready to start boiling that one might cause an eruption.

Yup, in the microwave, if there isn't something to permit the gas formation associated with boiling, it is possible to superheat the water (get it over 100*C). When you introduce something to the water while it is superheated, it vigorously boils....that champagne bottle effect.

The same can be done on the stove, but most cookware is more porous and has more surface irregularities that keep this from happening. Glass is a fluid, though highly viscous at room temperature (give then 100+ years, and you'll see the distortion in your windows as they flow with gravity)...and typically has a much, much smoother surface than most solids.

That's a persistent myth that has been widely accepted as truth since it's so bizarre and hard to contradict. Corning glass is probably a good source of information as to the alleged viscous properties of glass so I'll include a reference link to it that might save you some money if you ever bet that glass is viscous.

Pro Tip;

Prior to trying any sterilizing method involving boiling hot water, microwaves or other similar techniques, be sure to have removed the nasal pillows from your face.

Just sayin!
If everyone thinks alike, then someone isn't thinking.
Everyone knows something, together we could know everything.

I think windowpane glass from 100 years ago was all distorted. My Grandfather built his house (fairly expensive Craftsman, I think) about 100 years ago, and all of that glass was distorted, even 50 years ago.

I just ordered a so-clean sterilizer for my machine, tube and mask, will let you know how it does when I get it.
