In the Sam Raimi Spider-Man films starring Tobey McGuire, Peter Parker’s mutation allowed him to fire webs naturally out of his wrists.
This was a change from the original comics. In those, Parker created mechanical web-shooters – his mutation only brought him things like superhuman strength, the “spider-sense,” and the ability to climb walls. And, from what I’ve heard, that’s the way things go in the newer Amazing Spider-Man movies.
Anyway, in honor of the premiere of The Amazing Spider-Man 2 in Germany, inventor Patrick Priebe of Laser Gadgets recreated Spider-Man’s iconic mechanical web-shooters using a battery-operated laser and coil gun.
He fires the coil by pressing a switch on his palm, just like Spider-Man, and uses the laser to aim.
He’s a ways from webslinging through New York City, but Priebe says it’s just a proof-of-concept, not really meant to do anything extreme. In the video, you can see him fire pellets and a tiny harpoon thing.
Sytrofoam boxes, beware.
