I have one

I was building my first plane, a Tower Trainer kit. I forget exactly how it happend, but some how I let the CA glue drip from the bottle to my arm, once I noticed it after a few seconds I jumped up and ran for the sink and turned on the water... Well up until that time I didnt know of the big part that water plays in accelerating CA glue. After alot of pain, it was finally removed, but the mark stayed...
