Articles Required: One
sheet of glass, a little thin paper, silk cloth, two books, a pair of scissors.
Take
a piece of thin paper and draw a pretty figure of a doll on it. In height the
doll should be a little 'smaller than the thickness of the books you've taken.
Keep the two books separately at a distance and place the glass sheet on the
top. Put the doll under the sheet. Now rub silk cloth on the glass top.
As
the glass is rubbed, it gets electrically charged and attracts the doll. The
moment your doll touches the sheet, it also gets charged and is repelled. But
when it falls down, it's deprived of the charge and, as a result, is again
attracted by the glass sheet. So, as long as you keep on rubbing the sheet with
silk, this dance will continue.
For
better results do two things. First, bend the doll's feet a little and join to
the surface on which it's laid. Second, keep the base surface metallic—using
aluminium or some other light metal.
