-Dropper.

Method

-Fill measuring cylinder with 10ml of water.

-Add 10ml of water into a test tube.

-Add 5ml of water to 5 more test tubes.

-Add a small spatula of Potassium Permanganate to the first 10ml  test tube of water.

-Add 5ml of the water mix with the chemical from the first test tube into the measuring cylinder.

-After that add the 5ml of water mix with the chemical into the second test tube.

-Repeat to the remaining 4 test tubes.
