i have already made Flash's boots (the first command i published here) and Flash's ring (one of my newer ones). now i made my 3rd Flash item! it is the chemicals that gave Barry Allen his powers! the story is: Barry was experimenting then lightning hit him and knocked him into a cabinet of chemicals.
the lightning and chemicals mixed in Barry's body while he was unconscious. when he woke up all his injuries went away very quickly. then he saw everything in slow motion. that is how he became the Flash.
