Handmine
From Tardis Wiki, the free Doctor Who reference
Handmines were used on the planet Skaro during the war that lasted a thousand years. They appeared in groups, and would take hold of, and pull individuals underground.
As a child, Davros found himself surrounded by handmines. A soldier tried to help him, reminding him to stand still before being pulled underground. (TV: The Magician's Apprentice)
