Here the demo was great. However. I didn't catch the point that half of each wheel is charged negatively and half is charged positively (I thought, that "one wheel is positive and another is negative" - which is wrong). Will probably build a toy like this for myself: seems simple. P.S. As aPhD in chemistry I know that "mother Nature" might mistreat you if you disregard precautions. Colleagues, don't repeat it unless you are trained in the field.
The charge collected inside the jars is in contrast to that of an "uncharged" object, where "uncharged" means the object contains equal amounts of positive and negative charge (protons and electrons), for a net charge of zero (+c-c = 0). The outsides of the two jars are typically connected together so that as one jar collects additional positive charge inside and the other collects additional negative charge inside, then negative and positive charges, respectively, are attracted to the outsides via the connection between the two. Thus, the two connected outsides, considered as one whole item, remain uncharged (net zero charge), but we say polarization exists between the two. The outsides, considered separately, will have negative and positive charges. If the outsides are then disconnected from one another, they will retain these charges. As long as the outsides of the two jars are connected to one another, and there are no leakage paths from the Wimshurst Generator to the surrounding environment, the outsides of the jars as well as the interconnection remain at zero electric potential with respect to "ground" ("ground" being uncharged), even though the two outsides, considered separately, are charged. Perhaps I should have stopped when I completed the first sentence. I hope the rest is not too confusing. 🤐

Was clear the second time I watched it.
0:40 compared to what?
