Removal of a broken drill bit with alum

Dissolve Away BROKEN DRILL BITS with Grocery store supplies I thought some people may find this tip useful. I used Alum to dissolve away a broken drill bit in a brass part. The brass was unharmed. I found all the supplies I needed in the grocery store. I attached a link to a video I made about the simple process. I hope some people find it useful. -Adam
