Portable Induction Cooktop/Hotplate
Speaking of hot, how about a cooktop that doesn't get hot? Portable one- or two-burner induction cooktops produce instant heat that transfers completely to your cooking pot. The cooking unit stays cool to the touch. And because the heating element is a solid disc -- no exposed, glowing coils -- you can send one to college with your kid.
There's a catch, of course. If a magnet sticks to the bottom of your pot, you can use the induction heat surface. Otherwise, it doesn't work.
