The beloved video of 1996 Ig Nobel Prize winner George Goble igniting a barbeque in record time by using charcoal and liquid oxygen was unavailable for a while. Why? Because certain administrators feared that certain other administrators might fear that shadowy, barbeque-craving terrorists would learn something or other from it.
The video can once again be seen (unless the same or other fearful-of-others’-fears individuals have again exerted their influence).
(Thanks to investigator Gini Savetz for bringing this to our attention.)
