Hi. I really like the way you divulgate the science of electricity :-) I have a question I can not find an understandable answer...Could you quantify how much energy you can extract from a piezo disc, in relation from the energy you use to compress it? Thanks and best regards. Andrea.
I've had LEDs light up just from having the positive connected to the positive wire of a USB cable which was plugged in, and just touching the ground wire.

LOVE your videos!! In the process of going through a mold abatement at my grandmother's 3,200 sq foot house. Any chance you might do a video about DIY ozonator made using ozone plates or parts from Amazon? Looks like one could be built for about $160 vs the $2,000 for the pre-made ones available online. :)

Here's my first presentation in front of live audience! I covered:

- Which one hurts more, AC or DC?
- What kills, current or voltage?
- Can we weld with car batteries?
