“Bombing” von Akay & Brad Downey auf dem italienischen Fame Festival 2012.
what are they using to make the bottles explode?
I guess they’re using soda (Na2CO3). Works faster if you put some acide (f.ex. citric acide) in the coloured water first and than add soda.
The commentators at Urban Art Core are sure, they were using dry ice: http://www.urbanartcore.eu/brad-downey-akay-paint-bombs/
