In Marvel's Avengers, no one can pick up Thor's hammer but the superhero himself.
Now one man has built his own Thor's hammer and - like the legend - only he can lift it.
Allen then steps up to the plate and lifts it with ease.
But his skill isn't superhuman strength, it's his big brain: Allen is an engineer and created the hammer over four months with a powerful electromagnet that locks against metal surfaces. He built it with a fingerprint scanner that only recognizes him.
"The magnet will turn off if a fingerprint on the fingerprint scanner matches with mine," he told INSIDE EDITION.
His next project? A light saber in time for the Star Wars movie.
