Household batteries (the usual suspects: AA, AAA, C, D, 9-volt) can be recycled through battery retailers like Batteries Plus. While you save up enough old batteries to make it worth a disposal trip, keep your dead batteries in a dry place that's out of reach of kids.
Water temperature is vital. Doing it correctly, you can make what many say is the perfect cup of coffee. Ideally, you want the temperature between 195 and 200 degrees F. One way to do this is to boil the water and use an âinstant readâ thermometer from any kitchen store.
Before we do the visuals, let's have a primer on good coffee. 1  Fresh, clean, cold water to start. 2  Fresh roasted, quality whole bean coffee.  Coffee is best brewed at temperatures between 92 and 97C, or about 192F and 204F. Guess what - a kettle, just off the boil, once poured, is at the top end of this temperature.
