He did in the best way. By showing us water and salt by itself and asking which will conduct electricity better. Then revealed that neither alone can conduct electricity, but mixing them together bridges the circuit and lights up a lightbulb. For a 5th grade me it was quite a surprise.
That’s what’s up. All those old school science shows and classic Discovery channel is a big part of why I got into science / medicine. Learned a lot and got a ferocious curiosity from them.
Hope he explained the water isn’t what’s doing the conducting but rather the dissolved ions within. Pure, deionized water is a fairly good insulator.

It inspired me to become a human sized rat, but I’m glad it worked out for you too!!
