Weigh it and shake it.
Generally speaking, the quality of qualified children's art paint is about 6-7 kg for a barrel of 5 liters and about 25 kg for a barrel of 18 liters. We can judge whether the paint bucket is qualified by weighing it. There is also a simple way, that is, to lift the art paint bucket.
