I dropped the expanded copper shell and it bent a little, i put the shells back together, the small shell is now stuck in the expanded shell. I just got this. FFFFFUUUU How do i get it apart? is there a way to get the expanded shell unbent?
run some hot water on the shell - the heat may cause it to expand and come loose.
To get the dent out of the shell, put a smaller coin (a quarter will do) inside the shell, and roll it on edge on a smooth, hard surface. By applying pressure against the edge with the coin, you may be able to gently bend it back to its original shape.
