you're looking for something to do today then get charged up because
it's National Battery Day! How many devices will you be using
today that require batteries? Let's get right into
National Battery Day!
WHY IS THIS A
Today is a holiday that is set aside to celebrate the
the inventor who made the first battery: Alessandro Volta. Volta was
born on this day way back in 1745. Before we get into things,
yes, there is a dispute that the "Baghdad Battery" is the first battery
ever to be made but we're still not exactly sure what they used it for.
If it was used as a battery of some sort, then it would be the first.
back to Volta... he was an Italian physicist who discovered things like
methane. He also created the first electrochemical battery cell in
1800. He had a zinc electrode and a copper electrode and put them in an
electrolyte liquid, either sulfuric acid or salt water. The zinc would
react to the negatively charged sulfate and the copper would interact
to the positively charged hydrogen ions. The hydrogen ions would pull
electrons from the copper and form bubbles of hydrogen gas.
the zinc is the negative electrode and the copper is the positive
electrode and, if you connect the two, a current will pass through
them. And that's how the first battery came about. We've come a long
way since then, our batteries are a lot safer to handle and we use them
in so many different things. Can you really imagine life without
So how can you celebrate today? Well, you can do a simple
exercise and see if you could truly do without batteries for a
day. Go around your house and jot down ALL the things you use
that have batteries in them. Now go through that list and
off the things that you don't really need to use today. Do
still have things on your list that you didn't check off? You
can't go without them, huh? Well, then you have a great
celebrate this invention!
So why don't you go to the store
and pick up some batteries that you normally use on a daily
basis. It never hurts to have extras, just incase.
the things that you hate having run out of batteries. Things
your watch, remote control, flashlight, cell phone and so on.
it wouldn't hurt to replace the batteries in your smoke detectors
either, or at least have some on hand for when they start beeping.
Or you could do your own experiment to see what you can draw
power from. All you need is some zinc, copper, some wires and
then something that doesn't need a lot of power to run it.
Something like a watch or LED light. It's pretty cool to see
different things you can use for power, like the ever so common potato
clock. Regardless of how you celebrate today, I hope that
running on full charge!
