Slightly converse, I read that washing machines are heavy to damp the vibrations, and they use (ta-daaa) concrete blocks, adding to the shipping costs.

Device could make washing machines lighter and greener
A typical budget washing machine is weighted by 25kg of concrete to stop it moving while on a spin cycle.
The new invention is a sealable plastic container that is filled with water - but only once the machine is in place.
The team at Nottingham Trent University says the change makes machines easier - and cheaper - to transport.
By replacing the concrete with empty containers, the weight of the machine is cut by a third.

Nobody figured that out until 2017.
