If you've ever ripped a plaster off your skin you'll know it can really hurt.
But now a new plaster has been developed that scientists say is completely pain-free.
The new tape has the same glue and backing as normal plasters but has an extra layer in the middle that must be peeled back to remove the tape.
This leaves glue on the skin where it can be rubbed off or left to drop off.
The plasters have been developed to help hospitals looking after premature babies.
Their skin is too delicate to cope with the tough tapes used to attach breathing tubes and vital monitors and can be damaged when the tape is removed.
