This photo is taken when I make my first steps in chemistry as a student at school(10 grade).I didn’t understand much, but I was so exited, discovering this colours. Then I didn’t have any glassware and I mixed the reagents I this glass bottle, that was from juice. Now I study bachelor degree at chemical engineering in Razgrad,Bulgaria. 

At the photo you can see discoloration of KMnO4 solution, mixed with H2O2 and CH3COOH!
