Spinning Wheel

"Before the sun sets on her sixteenth birthday, she shall prick her finger on the spindle of a spinning wheel...and die!"

- Maleficent

The Spinning Wheel is an enchanted object which, when touched the spindle, will send its victim (in this case Aurora) into Eternal Sleep, originally death which was cast by Maleficent. The victim of the Eternal Sleep can only be revived by True Love's Kiss. It is used by Maleficent in an attempt to kill Princess Aurora in Sleeping Beauty.

Sleeping Beauty
The spinning wheel plays a major role in the film, because it is used by Maleficent to cause her curse on Aurora to be completed. Since Maleficent wasn't invited to the baby's christening, she casted an evil spell upon Aurora that, before the sun sets on her sixteenth birthday, she would prick her finger on the spindle of a spinning wheel and die. This caused lots of grief and sorrow on the kingdom. So King Stefan orders that all spinning wheels be burned. Sixteen years later, Maleficent hypnotizes Aurora and she transforms herself into the Spinning Wheel. Aurora touches the spindle and sleeps. Maleficent then captures Prince Phillip so he can't break the spell, but the Three Good Fairies manage to rescue him. Moments later he battles Maleficent and kisses Aurora which revives her.

Trivia

 * In the original fairy tale, instead of turning herself into a spinning wheel, the Dark Fairy disguises herself as a kindly old lady who offers to teach the princess how to spin thread, which is the way she trick her into cutting herself on the spinning wheel. The concept of fooling the heroine through disguise, however, was seen in Snow White and the Seven Dwarfs.
 * In Kingdom Hearts Birth by Sleep, the spinning wheel is not mentioned in the game. An unversed boss, the Wheel Master, is possibly modeled from the wheel. But whether the wheel became an unversed or not is questionable.
 * In the movie, when Maleficent shows Flora, Fauna and Merryweather Aurora lying on the ground, after she pricked her finger, it looks like that her neck was broken.
 * The spinning wheel is never mentioned or seen ever again, since it was Maleficent, who was the spinning wheel all along.
