Ok, the contest is officially over. Congratulations
@Hackerman, your guess of 7.77g was only .36g off from the actual weight of 7.41g.
I was surprised by how high most of the guesses were, but it's probably due to the fact that I have teeny tiny hands.
Thanks to all who participated in the contest and thank you to
@Krazy for making it happen. I'll let
@Hackerman and
@Krazy contact each other to work out the details.
