Purpose: This toy is called air cannon, and it is for children to play with. It sounds very dangerous but it can’t make any harm to the human body, because the things “cannon” shots are only air. So this toy is a cool toy for children that are able to “shoot” air.

Environmental Impact: It does not cause any waste to work, the energy it needs is only chemical, which is from the people who use it, so it does not impact the environment.

Precedents: On Youtube, I had see multiple designs that matter with energy transformation. The reason I choose the air cannon from those multiple designs is that it had shown up in the animation, Doraemon I look when I was a child.

Creative: In this product making I do not have my original element because on the internet there are detailed production tutorials, but on creative the most material need me to process and splice, all of them are raw materials.
