Because the Ant-Man suit itself apparently isn't cool enough, Hank also gives Scott an extra weapon: two coloured discs which can be used to shrink and enlarge himself. The red disc shrinks and the blue one "embiggens" anything they touch, which is a fine device to allow the filmmakers to have a little more fun with Ant-Man's interactions with the world around him. They also allow Scott to escape at least two especially sticky situations, and hopefully future Ant-Man appearances will include more zany creations like this, because they fit the film perfectly.
Stay at home dad who spends as much time teaching his kids the merits of Martin Scorsese as possible (against the missus' wishes).
