Wow, how long would it take for a drop to basically attack down to the bone? Would it carry on and drop out the other side?
What is strange is the more dilute solutions do the worst damage- so you don't actually feel anything until it seeps below the skin hours later. I did read of a case while at GE Semiconductor where it bored a hole through a wrist bone over a period of days. The person ended up in the hospital for quite a long time due to the toxicity of the HF in the body.
Here is a wiki link and it is pretty accurate:

People don't realize that the production of integrated circuits, solar cells etc. can use some of the most hazardous processes around. I used to work with gases that had a lethal threshold in the parts per million. All this for a Gameboy.
