Electronics & Water? What could possibly go wrong? WistrelChianti: Interesting to see the actual numbers and the nicely predictable constant 300 ohms/cm as well as the actual effect on electronics so a very good video in that regard. One thing I wonder though, I saw somewhere that the amount of current that can cause problems for a human seems kinda small, if you are used to playing around in 5V land. The reason why no one notices anything from a poking the business end of a 9V battery though is that it isn't high enough voltage to get past the resistance of your skin (plus internal resistance) and still deliver enough current to be in the problem range. If you throw 240V mains into the mix however, I have a feeling 100mA might be un-fun. I seem to remember small currents start to be a little unpleasant at around 45V?

This video reminded me with an experiment I did any years ago. I dispersed graphene nanoplatelets into a dielectric fluid to increase its thermal conductivity (way less than 1% by weight. I placed a computer power supply in the fluid after checking the electrical resistance of the fluid which was to high to measure, before and after adding the graphene. onceI powered the power supply, it smoked. I couldnt understand which components failed. You should try this experiment with graphite in oil. You might figure out the cause of such failure. Thanks you for great video.

what about water and its effects on parasitic capacitance. like the base frequency of an oscillator? i would imagine the capacitance is increased and this things like velocity factor and tuned circuits will now be out of tune? i would like to see someone calibrate a quartz clock at room temp to exactly 32768 hz/

Amateur!
Once you put your fingers into the destilled water it became not destilled, not even mentioning washing everything in destiled water before you put it in the container.
Your experiments mean and prove nothing. Educate yourself.

Wait is great Scott a refrence to the office, cause at the end of Michael Scotts movie there's a thing that says Great Scott. They do that in adult swim animations.

Actually putting charged wires in DISTILLED WATER can be dangerous. The King Of Random did a vid on that. On a side note RIP Grant Thompson.

At 03: 01 there is a mistake
Current flow is the opposite direction of electrons direction of movement
Electrical circuit 101

so if i throw the hairdryer in the bath while im also in it, with the hair drier being connected to the outlet, i don't get shocked?

I think the Arduino a fail immediately on immersion because the piezo clock crystal fails. Not because of water conduction
