Clean the outside of your pitcher with mild dish soap and water. This eliminates oil and grime that may prevent your magnets from sticking to the container.
Place a ruler vertically against the side of your container. Make five marks at even intervals down the side of the container. For instance, if your container is 10-inches high, make a mark every 2 inches. Repeat on the other side of the container.
Draw a spiral of superglue on the N side of a ceramic disk. Press it onto the container over one of your grease pencil marks. N marks the north pole of the magnet. Having this side facing in will negatively charge the water. Attach all of your magnets this way.
Allow the glue to dry overnight. Fill your container with water. Allow the water to magnetize for about 24 hours. It should taste "wetter" and smoother than water straight from the tap.
