Design a Childhood Toy #DES200#A1

The toy trumpet is one of my favourite toys when I was a child. So, I re-designed the toy trumpet. When I designed this toy trumpet, I have considered that some children from relatively poor families did not have enough money to buy expensive toys. Therefore, the designed toy is easy to manufacture and low price. In that case, children can make different tones by filling an infinite amount of water in a plastic water bottle. At the same time, when designing this toy, I hope musical instruments toys can cultivate children's interest in music.
