comment Why is there more steam when water is subject to less fire?
by the way, I suspect that even just water will have the same effect, as I remember just boiling some water in the cook pot and turn down the fire to lower level and keep it there, and steam came out a lot more than if fire was at high level

I thought if I look at the inside the flask and follow to the outside of the flash, it is all one piece of metal?

DCDC converter is "DC-to-DC converter", which is just a DC voltage converter?

comment How can a portable 5V battery charge another 5V battery?
so let's say, to charge these portable charger devices using the USB port... since USB port (from a PC or Mac) is 5V, and the device is 5V... does the device actually take the 5V and has to use some transformer to up it to 6V and then charge its internal battery?
