We were put into groups of 8 and were asked to collect one waste article each from inside the campus. We collected the material and started to sort it out.
We had various things like a ball, toilet paper rolls, thermo, left out tape roll, etc. So we decided to make a PIN BALL MACHINE.
The tough part was figuring out the mechanism but as a group we all understood it and made the final machine.
Final Pin Ball:
And yeah IT WORKS!!!! Come and play.. Air Benders Pin ball!
