Why does WATER change the speed of electricity?

The electrons are back! This is the first of three videos discussing electricity - what is it, how does it work, how do we use it? This first installment talks about the speed of electricity and electrical signals in wires. Next up is Ohm's law, and what resistance really does in circuits, and third, I'll be taking another look at the experiment featured on Veritasium last year, building on the first two videos to explore the mechanism that couples the two long wires with a little more scrutiny. Enjoy!
