We’re not talking about a real, beating human heart here, but a prop replica of the Arc Reactor in the movie Iron Man. Encased behind plexiglass with the “Proof that Tony Stark Has a Heart” line, the replica is highly detailed, featuring machined metal parts and copper wire to complement the high-intensity LEDs. This isn’t anywhere near as powerful as the fictional real thing though, since a quartet of AA batteries will last only 8 to 10 hours where the LEDs are concerned. You can place a pre-order for the Iron Man Movie Arc Reactor Prop Replica for $149.99.
