I will be looking for a diy version in the next issue of MAKE. Someone will put it together and sell it as a kit.

Back in 2005 I had to remove my own piercing at the small Erie International Airport. I think its was because the field is named after Tom Ridge.

Now my piercing wasn't a nipple one but an ampallang. ( NSFW photo on wikipedia ) I was allowed to go to the near by bathroom and remove it. Placed it in a ziplock bag and had to show it to TSA. I've been though the same airport other times and never had a problem. No other airport I travel through has ever asked me to remove my piercing
