the flying bottle cap

Some daily consumables, such as mineral water bottles, are often discarded after use. To some extent, this is a waste. This design, called "flying bottle cap", combines the toy of bamboo dragonfly with the bottle cap. When in use, the bottle cap can be transformed into a fun toy through simple operation, which is very suitable for children, especially children in poor areas. At the same time, the "wings" of the bamboo dragonfly are not useless before the bottle cap changes, but can facilitate people to carry the water bottle with their hands.
