Inside of the kit, you would also see a plastic spoon that you can use in order to get a part of your sample and place it inside the tube where you will be seeing the reaction in. Make sure that you wash this with soap and water everytime that you will use it so that it would not contaminate your sample.
There should also be a color chart inside of the kit or at the back of the box. The color chart is really helpful when you are trying to determine the identity of your compound since it will be the standard you would refer to when checking the time of reaction and the color of the product you will be producing.
Lastly, there is also an instruction guide inside the package to help you out in case you are a newbie at the kit.
