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, and watch as your creepy critter contraption drops on unsuspecting victims, er, friends. Explore the spooky science behind your sensor, then discover other marvelous machines that detect motion — just like your spider. This is one Halloween trick that’s a treat to build!
Check out the video tutorial and build along with us!
• Craft a spider out of yarn, a chenille stem, and up to 12 wiggle eyes!
• Get hands-on with engineering. Build the motor box using the included sensor (which sends a signal when it detects movement), transistor (which switches the motor on when it gets a signal), motor (which spins to drop your spider), and battery pack (which powers your spider’s movement).
• Includes spiderweb roving to customize your contraption and a mounting strip to hang it from your wall.
• Get creative! You can swap out your spider for any creepy-cute critter you make from at-home materials.
• 29-page booklet includes step-by-step troubleshooting instructions, a rundown of how your sensor works, and fun facts about motion-sensing alarm clocks, buses, and other marvelous machines.
• Spider box dimensions: 6.25 x 4.25 x 4.25 inches (15.9 x 5.7 x 5.7 cm).
From the desk of the product designer:
Behind the design
“We were inspired by spiders in the wild and 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.”
By the numbers

My grandson had a great time building this! His mom doesn’t like spiders so he loved teasing her!
It was difficult to get it to work at first but once working it was great!
The kids reported that it was a fun project, but it sort of went crazy then quit working.
