Reaction between sugar and concentrated sulfuric acid produces coal
The concentrated sulfuric acid can take the water out of the sugar molecule producing coal plus water according to reaction equation:
C12H22O11(s) → 12 C(s) + 11 H2O(aq)
That is a exothermic process and liberates poison's vapors, then take care and use one appropriated place , don’t do it indoors!

Classic Science Experiments: Egg in a Bottle
Classic Science Experiments: Egg in a Bottle
You will need: a egg, an empty milk bottle and some matches
The match warm the air inside the bottle
the air become less dense and go out. Since the egg close the bottle, the air inside cool and the inner pressure reduce. Thus the atmosphere pressure push the egg.
