Use a pipette with Art Clean to create interesting flowing reactions to the resin. Hand sanitiser will also react with the resin.
Blowing resin with a straw will cause colours to move around. For best results, do this where colours are laid on top of one another or where two colours meet.
Dyes & Popsticks
Dyes can be dropped directly on to areas of resin then dragged with a Popstick to create marbling effects. Note: they are highly pigmented so only use a minimal amount.
Use a Giant Popstick on its side to wipe large areas of the resin around the surface.
