Does watching your child eat food off the ground make you cringe?  Well cringe no more!  A friend told me about this research and the premise intrigued me.  These college seniors proved that the 5 second rule could be changed to the 30 second rule and in some cases the 1 plus minute rule.  Though seeing my daughter eat a Goldfish cracker off the pavement will still be unsettling, it will not make me lunge towards her to pry it from her little mouth. :)
