Emma lost her eye to a deadly cancer and has now revealed she's now able to blow out candles through her empty socket.
Emma Cousins has been living with one eye after undergoing an operation in 2018 to remove a rare tumour called a mesenchymal chondrosarcoma.
While waiting for an operation to patch up the hole, which is connected to her lungs, she has created TikTok videos of her using the hole to perform her newly-found party trick.
