Duct Tape

Appearance

History
Greg Universe tries to use it to fix his van along with his leg in the episode House Guest, expressing that "Some well place duct tape can patch up anything in a pinch." Later in the episode he, along with the help of Steven's magical healing spit, manages to seal the geode with more duct tape. At the end of the episode its assumed that the duct tape now has magical properties based on the sparkles around it (similar to the ones that accompany Steven's magical spit), along with Greg's wink and suggestion to Steven "Just in case you have trouble again."
