 Rex has his old Hourman costume, and a bowl full of Miraclo inside a secret compartment of the grandfather clock in his bedroom which opens when both hands are turned to 12.Due to the addictive nature of Miraclo (he later invented a non-addictive formula), the way that Hourman accessed his powers changed somewhat over the years.At one point in his career, he would use a black light lantern (similar to the Golden Age Green Lantern) that would activate a residue of Miraclo still in his body.
