Let me phrase my question differently.
Yes, it’s obvious the pucks are made of an ordinary substance and the folks who created them make no effort to hide this fact.
But what is rather novel about them (to me, at least) is their ease of use by just throwing them up on the roof.
I wouldn’t have the foggiest notion of how to wrestle those crystals into a solid shape for ease of tossing up there.
If someone else has an easily accomplished DIY method, I’d be very interested. But it has to be easy enough to dissuade me from the ease of just ordering them from the website or buying them at a local home improvement place.
And if there is no easy DIY method to put said crystals into a throwable solid shape, it really wouldn’t make much difference what substance they’re made of. It would totally be a moot point.
My question is, how is merely knowing the properties of salt and ice “helping” me?That knowledge wouldn’t make one iota of difference in terms of the practical problem of getting the salt on top of the roof.
When I went to the website and read about them I did recognize it as a form of salt. But so what?
Even tho I was aware of the ice melting properties of salt ( I do live in MI, after all) if I needed to melt it off the roof I have absolutely not a clue how to do that (apart from these clever little pucks)
So, my point was that what makes them unique and clever is NOT the common ingredient from which they’re made, but rather the solid FORM or SHAPE.
Unless I can do the same process which they do to enable them to be thrown the required distance, just knowing the basic chemistry of ice and salt does not enable me to “help myself” regarding the roof.
Again, if anyone has a DIY method, let’s hear it. Otherwise I’ll be ordering from them. Not because I think they have some magic ingredient but because they put it into a unique form enabling easy use on a roof.
