OK, then it's definately not duct tape. Duct tape is the exact opposite of destructive. Did you get a pet Scootaloo?
Ok... here it... is... you ready! Spoiler: the great thing! I get to go into DT blind! My glasses are being re-lensed so I have to go without them! Destructive because I get to use dangerous machinery!
meh the most destructive thing i have is my IKEA kitchen knife which just gave me deep cut right into my pinkie... Edit: im not dying though, but the meal im cooking will have a bit of blood in it.
