Leonard W. Fine · NASA Technical Reports Server (NASA) · 1996
This laboratory procedure starts with a violet suspension of an 'alfin' catalyst being added to a bottle containing a solution of 1,3-butadiene in pentane. The bottle is corked and shaken for several seconds. The mixture sets to a gel, and within 2 minutes the contents erupt from the bottle.
