Cash FX update: The recap this morning has certainly paid off!! We had 2 original guesses at 9 a.m and 10 a.m. however both were incorrect. The mystery sound is not the buttons on a blender and is not the knob on a stove clicking off. $1250 up for grabs at 2 p.m. and 3 p.m. Simply identify the mystery sound and the money is yours!
