Students design 'Mitt' prosthetic limb for children
Even the most up-to-date prosthetic limbs can often be too heavy, or hard for young children to use with ease.
But now, a group of Imperial College engineering students has created a new, lighter one.
The flexible device called the 'Mitt' slides on like a glove and has magnetic attachments for extra movement.
It's led to a campaign to give one to every child, under the age of nine, who needs one in the UK.
Duncan Kennedy met a seven-year-old girl who's received one.
