I don't know how this magical appliance works but I do know I need one.
Someday I want to coat my whole arm in icing and dip it in a vat of sprinkles. I wouldn't know what to do next, sadly, once I'm thoroughly spackled with hardening icing and sugary bits. I wouldn't want to eat it, I just want to take pictures of it maybe and call myself "Ol' Donut Arm". I guess just a donut will do.
