Magic Pictures !


Articles Required: Two books, one glass sheet, cork, brush, a little glycerine.

With the help of brush and glyce­rine, make a figure on the glass sheet. Now, show it to the specta­tors from the reverse side. And take care to keep the light source also on the reverse side.
First grate the cork into fine, smaller pieces. You can do this with the help of a grater used in the kit­chen. Put these pieces between the books and then draw the figure on the glass sheet as described above. Now lift the top book and put glass sheet on the cork pieces with the glycerine-coated side facing downwards. If you start rubbing the sheet' top with woollen cloth, it would be charged with electricity.. As a result, the cork dust would get stuck to the glass. But when the rubbing is stopped, most of the dust would drop back on the table, except from the glycerine-coated part.

Now lift the sheet and blow off the extra cork dust around the figure. Your picture is ready. A magic pic­ture for those who don't know the secret about glycerine!
