2. With a litre or 500 ml jug, (marked) fill it up with the bucket of water and make sure it is precise to what measurement you want

3. Pour the water into the bottle into the 100 ml or 200 ml cup and make sure it is exactly right

4. If it is, pour it into the bottle and mark lightly with a pencil pour it back to the 100 ml or 200 ml to double check it’ s right. If it is pour into the bottle and mark with a permanent mark and add the mls

5. Keep on going and if it is more than 200 mls, use the litre jug. With the paper towel, wipe the masking tape just incase it fall off. Also wipe the work spot that bottles been on. Now there should be a marked bottle or container with water in side. TIPS
