This is the thread for all discussion concerning the "2013 Mad Science Fair Prop Challenge."
Please refer to this thread for the official rules.
Everyone be completely aware that winners from the previous challenge (2013 $20 Prop Challenge) are not eligible to win prizes in the current challenge. You may still enter, but your entry will not be in the running for a prize.
Feel free to ask questions, make comments and by all means... talk amongst yourselves.
