Battery-in is a new battery recycling bin,which aimed to encourage people to recycle batteries.
If waste batteries are disposed as common rubbish, it will bring about secondary pollution to the soil. But people are often too lazy to classification recycling
To motivate people to recycle waste batteries, we design Battery-in based on Galton Board. When users put waste batteries from the top of Battery-in, batteries will first pass through a Galton region and then fall into a certain part of the bottom. When they fall into the red, a brand new battery will be rewarded as bonus.
