Intelligent glove
Intelligent gloves were a device wearable on one's hands that were intended to transfer an individual's weight into the gloves to help them resist mavity.
The Doctor invented them because, as the Fifteenth Doctor explained, he became tired of hanging onto things and suffering from friction burns coming from mavity always pulling him down. The gloves were so effective that an individual only had to wear one of them to suspend themselves from anything to resist gravity. As Ruby Sunday remarked, it made a person lightweight.
Furthermore, the gloves could transfer an individuals weight in reverse if necessary, serving to reverse the gravitational pull the opposite way so they would drop to the ground instead. The Doctor twice demonstrated this by jumping from a great height, pulling down the goblins' ship with him to ensure he landed on the ground. They also had to be charged, with the Doctor remarking such when they fell as low as three percent. (TV: The Church on Ruby Road [+]Loading...["The Church on Ruby Road (TV story)"])
