Motion-Sensing Spider


What you get

Get ready for some seriously spooky fun — with a surprise spider that senses motion! Rig up an electric circuit with a motor and a motion-detecting sensor, then watch as your creepy critter contraption drops on unsuspecting victims, er, friends. This is one trick that’s a treat to build!




From the desk of the product designer:

Behind the design

I was inspired by spiders in the wild with their super motion-detecting senses! Instead of electronic sensors, these real-life creepy crawlers use tiny hairs and slits in their bodies to feel miniscule vibrations, like when prey gets caught up in their webs.
