THE new plastic £5 notes can be rubbed out with a simple pencil eraser.
While the new banknote was promoted as being twice as durable as previous bills, an experiment on the notes has revealed almost the entire note can be rubbed out.
The face of the Queen can slowly be erased, while the "Bank of England" and even "£5" disappear when they are targeted with the rubber.
Winston Churchill also can't escape the fate of being rubbed out, with the former Prime Minister's eyes, nose and lips slowly disappearing.
All that remains is the hologram and security number.
A Bank of England spokesperson told The Sun Online: "We design our banknotes for typical day-to-day use including being folded into wallets and scrunched up in pockets.
"Our new polymer notes are more durable than paper and went through a series of rigorous tests before issue. A banknote is not indestructible if someone intentionally sets out to damage one."
The new notes are made of polypropylene, a thin and flexible film that is designed to last longer and not get as dirty as other paper notes.
The thin film is then coated in an ink layer which allows it to show the note's necessary printed design.

The revelations come after people have been cashing in on the new plastic notes - while others have been conned out of thousands of pounds.
Gareth Wright thought he had struck gold when a note with the serial number AK47 attracted a winning bid of £80,100 on eBay.
But he has been left empty handed after the buyer recently revealed he was a drug dealer.
The penny dropped when the trickster said he wouldn't be paying up because he was "waiting on a cocaine shipment".
Poor Gareth’s hopes of buying his mum’s house and then travelling to South America off the back of a fiver have now been dashed.
Notes with the serial number AK47 are particularly popular thanks to wannabe gangsters and the machine gun connotations.
However, the online auction site is under no obligation at all to ensure buyers pay up.
There are ways to cash in on a new fiver though.

The new plastic fivers fetching the highest prices are the ones that contain serial numbers beginning with 'AA01'.

The first note – featuring the serial number AA01 000001 – was presented to The Queen which means there are up to 999,998 other fivers with the AA01 prefix.
The ones that fetch the biggest bucks contain serial numbers starting 'AA01' - meaning they were produced in the first batch.
The serial number can be found on the reverse side of the note, which features a portrait of Sir Winston Churchill. It is printed down the left hand side and also appears in the bottom right below the clear window.
