Water & Toothpaste
… I think they do not mix, at least not voluntarily. So who came up with the idea to hold your toothbrush under the running tab for a while and then sticking it in your mouth while the water keeps on flowing?
That makes absolutely no sense. Water does not ‘stick’ to the toothpaste, or at least not in any noticeable amount. So, let’s just make it easier for ourselves: if we do not open the tap before we are finished brushing, we also do not have to remember closing it… better for everybody, as 2 minutes (recommended brushing time) of useless flowing water is a lot of clean drinking water wasted.
