And, on a somewhat related side note, the makeshift travel edition of my shampoo/conditioner:
I re-used the bottle and just put apple cider vinegar in it, and then as you can see, the bag is full of baking soda; all I need is water. I hope I calculated my amounts correctly, and if not, it's not a huge deal to find some more of this stuff. I tried to find an old pill bottle, or something equally small, to put the baking soda in but alas, I could not find one that was empty. The bag I used, however, is re-used and will never be tossed as long as I'm in possession of it.
Now, in theory where I'm going will probably have baking soda but I figured I might as well bring it, just in case. And, the plan is to find a cup, or two, where I'll be staying (which shouldn't be hard) and then I'll be able to mix the goodness and bask in the glory that is.
Just hoping security likes this idea as much as I do. If only I could powderize, aka dehydrate, the apple cider and I'd be at an even higher level of good to go-ness, with no risk of spillage.
