Anyone sell me ball zinger or materials

Hi, i’m trying to get ball zinger, either the materials or the whole thing, i am willing to pay well for it if anyone has extra materials from theirs. I live in uk and noone over here sells the zinc, have even tried metal foundry but no luck. please help

I wonder if a zinc plated bolt would work for the ball zinger? I don’t know if anyone’s tried that before.

I don’t think the zinc plated bolt is a good idea, as it is likely to have heavy metal contaminants such as lead.

I considered that. But how likely is it, and would the amount of trace contaminant be a problem. You wouldn’t be ingesting the bolt.

car batteries. watch the acid though
