Is stirring the water necessary?
No, you can either stir the water, from a glass to a gallon, for 20 seconds, or just leave the wand in the water. It will not overcharge the water, nor shorten the life of the wand. If the container is larger than a gallon, like say a water cooler, either stir longer or just leave the Stirwand in the container, just as you would simply drop in fish tanks or place in ponds, watering troughs, etc. A single Stirwand is enough for up to 500 gallons. If you leave the wand in your water bottle, just be careful of your teeth. The Stirwands are very sturdy. Kids are often attracted to the Stirwands – don’t let them chew on them. If stirring, obviously, the end containing the minerals goes in the water. The minerals do NOT leave the container – it’s the energy of the minerals that does the magic.
