We see a lot of pips and peels of eatables around our roads and this simple and ingenious toy can help making our surrounding clean. 
With just an A-paper and a tape we can make a sack to hold the eatable and store the shells neatly in another compartment. This costs nothing but can greatly reduce the plastic waste.
So next time the shopkeeper seller gives you a plastic bag show them your paper sack and help the environment.
Take an A-4 sheet and fold its long edges to the mid-line. Tape the joint. It will become like an open paper pipe. Now fold 2-cm lines on both edges of this paper pipe. Then reverse fold them inwards. This will provide the necessary thickness to the storage sack. 
Now we will fold the sack – not in the exact middle but a little off centre so that one arm is bigger than the other. The bigger arm or chimney will store the groundnuts. The shorter arm will hold the shells.
We can try and make the sack thicker. How much should we fold on the sides so as that our sack can hold most amount of food? On other words how do we maximize the volume of our sack?
