A plastic ruler is rubbed vigorously with a woolen cloth
objects can be negatively charged when it is rubbed with another object; a woolen cloth for example. this is because the electrons from the woolen cloth will be transferred to the object which is being rubbed! only electrons can be transferred to the object and make the object becomes negatively charged.
Static charge
The balloon will gain a negative charge and the woolen sleeve will gain a positive charge.

The polythene becomes negatively charged.

the sand would stand up
Long long ago even before christ some 500 BC Thales, a great philosopher, found that when amber gets rubbed with woolen material then the amber is capable of attracting small pieces of dust.

Insulating materials can acquire a static electric charge. Rubber balloons, when rubbed on woolen cloth, are a perfect example.
when woollens are rubbed with your skin,static current is produced between your skin and the cloth.This static electricity is responsible for the crackling sound...:)
Woolen clothing is hot in the summer--woolen is an adjective.
