How to Make charcoal (carbon) by the dehydration of sugar

HOW TO:
1. Add few grams of sugar to the beaker.
2. pour about the same volume of concentrated sulfuric acid to the beaker.
3. stirrer the beaker then stay away and wait.
4. Huge volume of pure charcol is then produced.

CHEMISTRY OF IT:
It is very common reaction which demonstrates the dehydrating and oxidizing properties of conc. Sulfuric acid. Sugar is first dehydrated to elemental Carbon and steam, Carbon is further oxidized to Carbon dioxide, sulfur dioxide also produced by reduction of SO4 2-.
