This intricate Rube Goldberg device is designed to open a tea jar with a paint can lid, ensuring Granny's nails stay intact! The process begins with a compressed spring that releases a ball, converting potential energy into kinetic energy. The ball rolls up a ramp, gaining gravitational potential energy, then changes its velocity to trigger a series of energetic transformations through six clever steps. The final step drops an arm, using a lever mechanism to pop open the tea jar. Watch the magic of energy conversion in action!

Don’t Let Granny Break A Nail! A Rube Goldberg device that opens a tea box.

The Machine • This machine is designed to open a tea jar with a paint can lid.
First Step • A compressed spring is released, changing energy from potential energy of a spring into kinetic energy of a ball.
Second Step • As the ball rolls up a ramp, its kinetic energy is changed into gravitational potential energy
Third Step • When the ball’s velocity changes from positive to negative, the potential energy is converted into kinetic energy
Fourth Step • The ball rolls into a cup which drops. The force of the ball and cup then pushes a string.
Fifth Step • The string moving pulls a support from underneath an arm, which makes the arm drop. This step converts potential energy into kinetic energy.
Sixth Step • The falling arm hits the screw driver which acts as a lever opening the tea can
Eureka! • The tea jar is open!
Conclusion • The jar top is popped open from energy changing in six steps. • Any Questions? • Thank you
