Mass = Energy = Time

This piece of work uses weight mechanism clocks. The weights on each clock have been replaced with foods of the same mass.
The clocks work as normal now being powered by the gravitational potential energy possessed by the different foods

1.70kg of bananas (8 bananas) hang from each side of this clock, they gradually drop down losing gravitational potential energy.
This clock will last for one week before the bananas will have to hoisted back up to the top, it is not known how long the clock will last before the bananas decay
2.80kg loaves of bread hang form each side of this clock, they gradually drop down losing gravitational potential energy.
This clock will last for 24 hours before the loaves of bread will have to hoisted back up to the top, it is not known how long the clock will last before the bread decays
