Big idea: Nowadays, we consider a fruit's appearance when purchasing it, trusting our gut judgment as to whether or not it is healthy on the inside. Most of the time, we only check to see whether it looks nice on the outside before adding that fruit to our basket. We don't know the fruits inside, and sometimes we get an unanticipated outcome where the fruit has gone wrong from the inside out. Therefore, we decided to work on a project (a sensor gadget) that is based on people's health and assesses how the fruit is inside and out while also being portable so we can bring it with us wherever we go.
