I am going to teach you how to make a filter for when your electricity goes out. This is a good thing to have because I am always scared that if the power goes out I would have to change the water constantly.

Step 1: Materials

-Water bottle (empty first)

-A battery-powered bubbler

-Filter sponge

-Ceramic media

-1 or 2 suction cup

-Air Line Tubes

Why not store activated charcoal as well, or instead of the ceramic? In an emergency, the charcoal has other purposes as well.
