Each Tuesday we highlight one of the many unusual objects GRA collects through its various research projects.
Do you know what this object is? This week we’re doing something new. Leave your guess in the comments and you will be entered to win a free GRA jumpdrive!
Leave your guesses in the comments and come back Thursday when we’ll reveal the answer!
Rules: One entry per person regardless of the number of guesses. The contest is open through 12:00 PM on Thursday. Your guess must be left in a comment on this blog post. All entries will be compiled into a list and the winner will be picked by a randomized number generator.
