dea 1: fan bell (mechanical to sound)
Rating: 5/10 difficulty
Attach a fan with a bell in a way that when wind passes the fan, the bell rings.
Idea 2: steam bell engine (heat to sound)
Rating: 9/10 difficulty
Have a pot of water that will boil under heat, triggering a bell.
Idea 3: water mill engine (mechanical to electric)
Rating: 6/10 difficulty
Have a water mill that spin magnets to generate electricity, eventually powering up a lightbulb.
Idea 4: balloon car (Elastic potential energy to kinetic energy) (choosing this due to nostalgia)
Rating: 6/10 difficulty
Having a car that acquires its power from a balloon.

Target Audience:
The balloon car is made for everyone with passion to hand-powered vehicles and are fond of balloons. The car could also be used to learn physics, therefore, is suitable for every student.
Success Criteria:
- Finish the product by the last 2 lessons of the unit.
- Have the car go at least 3 meters without pushing it.
- Have a simplistic design that is visually appealing.
