I agree with Da Haze Meister. What I did was shove a 1/4 inch socket onto a empty bic pen (fits perfectly but I taped it there anyways). Then I took one of those things that hold tea bags, they're like little pouches with tiny holes all over them, and cut a small circle out of one side. Then I shoved the circle into the socket as hard as I could so that it was basically stuck in there.

Tin foil doesn't even sound like a good idea....
