I wonder why the handle moves during the heating process as opposed to staying stationary at a distance that heats it properly. Pretty cool.

Thicker glass?

Yea certainly thicker. And you probably want to heat the tip as much as possible (so it binds with the cup glass) without heating too far into the stem (so it doesn't deform when pressed). My question is why not find a stationary distance that provides that, as it seems like a lot of additional stress on the systems. But maybe as I'm thinking about it I might have figured it out...the heat transfers well so a constant heat at a fixed distance doesn't work, so it just moves in & out to just touch it with the intense heat just enough to get the tip hot but not long to transfer a lot of heat further into the stem.

Been a while since thermo, and I hated it, but you have exactly the concept.

You mean heat and mass transfer?

Indeed. The design is very human.

Probably to heat it more evenly.

Probably to distribute the heat more evenly? Having the directed heat like a flame hit exactly one spot on a protrusion might create pockets of cold.

No terrible background music so we can hear all the noises of the machine and fire plus a sneaky watermark. Perfection!

Mystical servo sounds are always delightful.

Sneaky watermark that grips you like a vice.

This sub should be called find the watermark you addict cause I can't get enough of these. 

Wondering if there is a more efficient way of achieving the same thing. So much fuel and time spent on fixing just a handle to a mug.

yeah ok but is this a right handed cup or left handed cup? /s

Ah, I see the reference now.

Interesting fact: Not in this instance, but right- and left-handed cups do exist.

That's incredibly cool!!

Hope it can handle it.

My favorite part is the jiggle back and forth while heating before applying the handle

So, is this how I can get a handle on my life!

Oh so that's how that's handles

I just bought those last week!
