Rereading the text, how does this save anyone from needing to buy soap? It just delays it by a day at most, by using up that last sliver. Which I use anyway!

And #1 does not make a "speaker" - it is just an iPhone holder, it will do nothing to amplify the sound ...

And the #11 one does not seem like it would help one bit. Sure the paper towel will be frozen, but the stuff inside won't get any colder any faster ...
