London-based Latvian designers Arthur Analts and Rudolph Strelis have made a series of bowls from shredded money.
They obtained notes from the Bank of England that had already been taken out of circulation and destroyed, then used them to make papier-mache containers bonded with resin.
It took £1000 worth of notes to make the smaller one and £3000 to make the larger one.
They're lined with white gelcoat so people won't be put off by the material's grubby appearance and the bases are conical like a spinning top so they never rest flat.
"Money bowls reflect the thin borders between valuable and useless, stable and variable, ancient and contemporary," says Analts. "Stability - one of the bowl's basic principles - is taken out. When the bowls are spun, they can rotate for up to two minutes, symbolising the change and rotation of the cash rate."
The project was shown at Clerkenwell Design Week in London last month - see all our stories from the event here.
