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.
Coffee begins to loose its flavour after it is ground, so it is best to grind the beans just before you will brew it. The longer ground coffee sits around exposed to the air the faster it becomes stale. Coffee companies want you to enjoy their coffee at it's best flavour, so they put an expiration date on it. This way you will want to brew it and drink it while it still has it's best flavour. So it is safe to drink, although it might not be at its best. Source(s): midnight Â· 7 years ago.
