Welcome back to Science Adventures
everybody! In this week's episode, I'm
going to show you guys how to harness
the power of the humble potato. I'll
also explain some of the science behind
it now this experiment can be a little
bit tricky but don't give up, sometimes
science is a bit of an art form as well. So
let's go to the set up and show you how
it's done.
Wasn't that amazing?! That was so good!
So the key point to remember in this
experiment, everybody seems to mess up,
is the potatoes aren't actually MAKING
electricity. The electricity comes from a
chemical reaction between the copper and
the zinc electrodes. The potato in the
middle is just acting as what we call a
salt bridge or an ion bridge for
electrolyte ions inside the potato to
flow from one electrode to another, and
that flow of electrons creates
electricity. If you want to look more
into it in more detail, have a look at
what we call the GALVANIC CELL or more
specifically, for copper and zinc, its
called the DANIEL CELL. So look into
those and you'll find out loads, loads
more interesting information about how
they really work. All right, I'll see you
next week. Don't forget to LIKE and
