Answer 2

U can take water in glass and take cardboard slighty larger than glass mouth .make 2holes of cardbord(have 3cm distance between them)attach 2pencils(sharped from both sides)in the holes of cardboard. half part of the pencil should be in the water and half outside. Take battery. Attach one wire to one pencil and second wire to second pencil. After some time you can see bubbles forming on pencils. Where the bubbles will be more it will beH2O and where bubbles will lees it would beO2.
