I was tempted to say something similarā¦ If youāre tickling the dragonās tail, running wonāt help once youāve dropped the screwdriver. 
(Iām not sure where I saw it, but I heard there was recent research that indicates that the Core wouldnāt have reached criticality without Slotinās own hand covering it and adding reflectivity. Being hands off during the demonstration would have made it even more difficult to control, but otherwise seems to be pretty good advice in general for exciting things along those lines.)
(Ah-hah, found it!)
