A foot detox machine is a relatively new invention that supposedly take the impurities, toxins and metals out of the pores of your feet by soaking them in a salt bath while introducing a very small, imperceptible electrical charge. Whether this device actually works or not is irrelevant, as people claim to feel better afterward. The downside, of course, is that these machines can run anywhere from $50 to $100 and higher, but you can make the same thing at home for much, much less.
Making the Bath
You will need are two 9-volt batteries; three 2-foot long lengths of wire, two alligator clips, two stainless steel spoons (or silverware), two basins (large enough each to put one of your foot in, along with water), and plumbers/electrical tape. To prepare yourself, tape one spoon to one of the lengths of wire with your plumber's tape. Do the same with the other spoon with another wire. On the opposite end of each of the wires, tape an alligator clip. Make sure that the metal of the alligator clip is connected/touching the metal of the wire, and the same for the spoon and the wire. This won't work if the metals don't touch and create a current. Connect the alligator clamp of one of your wires to the positive connection of your battery, and the other alligator clip to the negative connection of your other battery. Use the third wire to connect the remaining two terminals together--one battery's positive, and the other's negative. After this, create your detox solution.
Creating Detox Solution
An easy detox solution recipe to soak your feet in, involves combining 1 cup of epson salt, 1 cup of sea salt and 2 cups of baking soda into an airtight container. Fill your two foot basins up with water so that when you place your feet inside, they won't spill over. Add 1/8 of the solution to each of your feet's basins, and then insert your feet. This, in itself is supposed to be detoxifying, but to increase the effect, simply add 1 spoon to either foot, and you have completed your foot detox machine. Don't leave your foot in for more than 5 to 10 minutes the first time. After you've done this a few days, you can leave your feet in for up to half an hour. Remove the water and spoons after every bath, and use clean water and fresh Detox Solution every time.
