Cork USB/Pen Drive

In this Instructable I'll show you how to make a cork USB. this can be a bit tricky when hollowing out the cork.
WARNING: hollowing out cork is dangerous is knife cuts through cork. Some hot glue guns may be too hot and could damage your USB memory. I'm not responsible for any damages (to you or your USB).
