I have used this tape in a few college classes to teach simple paper circuit critical making. Copper is always a beautiful addition to a paper project. It's a little tricky to work with; it tends to bend and kink, and sometimes the glue can cause conductivity to glitch. For the intro classroom, though, it works well enough when combined with some Chibilight LEDs and batteries (I'd recommend buying them all separately; it works out substantially cheaper than springing for a full Chibi kit per person).
