[QUOTE="Boulders, post: 299458, member: 9024"] Hey Scott. I would recommend that you put a rod in there instead of a string and print a cap for it you can fit on the end. Then put a spring on the rod on the outside so u need spring action to push the magnets down against the black sand and when you release it it will retract back up on its own. Just like the commercial black sand magnets are designed. [/QUOTE]
