Wait... Idk then :P Good save.
Ya. But I think somehow the fireworks got set off, giving different colours to filt... which then colours the dust, blows them out after they react with neutrons...
You decorated the contents rainbow, I think and Neutrons have the ability to creat fireworks (grey) only with dust. NEUT + DUST = FWRK
Its first fireworks being ignited by neutrons.
