An electroscope is a device that detects and measures electricity. In experiments involving a pinball electroscope, the pith ball moves because of an induced charge.
It is a very light, nonconducting, substance that is used to demonstrate electrostatic forces. Typically a small amount is hung at the end of a string. When a charged rod is brought close to the pithball it polarizes the pithball molecules. That is, it attracts charges that are opposite the charged rod and repels the like charges. This causes the molecules in the pithball (which has zero net charge) to slightly rotate so the unlike charges are nearer the surface and closer to the rod. When this happens, there is a net attractive electric force on the pithball which causes it to swing (slightly) toward the rod. If the pithball touches the rod it will pick up some charge from the rod. All of a sudden it now has a net charge, which is the same sign as the rod's charges and the pithball will swing (strongly) away from the rod because like charges repel. The pithball was originally made from dried pith, a soft spongy material found in the stems of plants. Nowdays, lots of materials will work; dried corn cob, styrofoam etc. The requirement is that it be lightweight (so it will easily swing when subjected to the electric forces described above).
Electrostatic charge.
During induction, if the ground connection was removed first before the charging body, the electrons on the electroscope will be stranded. This causes a negative charge on the object.
It causes tornadoes

electrons jump onto or off the neutral ball when a charged object comes close to it

Electrostatic charge.
slowest,causes the ground to twist and bend.
Falling overboard and drowning. The major cause of fatalities involving small boats is drownings from falling overboard
Improperly or overloading the boat causes most boating accidents involving sportsmen.
They believed in supernatural causes involving the displeasure of Gods
Intoxication and inexperienced. Add stupid and that may cover 90% of the accidents.
More than 95% of all cases of SVCS are associated with cancers involving the upper chest.
