Cool and Creepy Spider Bots | Halloween STEM
True story — even though I wrote a book about backyard creepy-crawlies, spiders still freak me out a little bit. They are unpredictable and move way too quickly for me.
They’re perfect for Halloween, though.
I’d been planning to make brush bots with my kids for awhile, so I already had the motors and batteries on hand, but the little plastic spiders I found in time for Halloween just made them so much cooler!
To make yours, you’ll need:
- Button Batteries
- Micro Motors
- Tape
- Double-sided Tape
- Toothbrushes
- Small Plastic Spiders
- Strong Cutter
- First, cut the handle off a toothbrush.
- Cover up the top of the brush head with washi tape to match or stand out against your spiders.
- Tape one of the motor wires to the bottom of your button battery.
- Tape the battery with the wire side down to the top of your toothbrush head with the same tape you used to cover it.
- Put double-sided tape on the underside of your spider and tape it to the button battery, leaving a bit of battery exposed for the other wire.
- Tape the second motor wire to the top of your battery near the spider, covering the rest of it with the same tape you used on the toothbrush.
- Let your spider bot loose on the table or the floor and repeat with the remaining materials.
Have fun! These creepy spider bots are fun and addicting. That tiny motor works just hard enough to shake the bristles of your toothbrush, turning them into a bunch of little legs.
