I don’t know about you, but moving parts make play and learning a lot more fun for my kiddo. Carving pumpkins is super fun, but making a pumpkin robot is even better. Enter these Halloween Pumpkin Brush Bots. They’re a fun and festive way to introduce circuits and motors to your kiddos. Oh and they’re really silly to watch twirl around the table… This post contains affiliate links.
Halloween Pumpkin Brush Bots Supplies Needed (1 set per pumpkin)
- Styrofoam pumpkin {affiliate}
- 3VDC micro-vibration motor {affiliate} or motor from an electric toothbrush
- Angled head toothbrush {affiliate}
- 1.5V or 3V coin cell battery {affiliate}
- Googly eyes {affiliate}
- Masking tape
- Sharp knife
- Wire cutters
- Glue gun
SAFETY NOTE: Coin cell batteries are extremely hazardous if swallowed. Please keep away from children who put non-food items in their mouth.
- Cut the head off an angled toothbrush by pinching the neck in a pair of wire cutters and bending back and forth until it snaps.
- Cut a hole just big enough for your toothbrush head in the bottom of the styrofoam pumpkin. Then dig out enough space so that the motor won’t hit the styrofoam and stop moving. This may take a bit of trial and error. For little kids, you might want to make this a grown up job since a sharp knife makes it a lot easier.
- Decorate your pumpkin. Googly eyes and black foam are easy add-ons and a glue gun makes it super quick.
- Tape motor to toothbrush head with masking tape. Play around with motor placement and direction as these make a difference in how the brush bot moves around. Note: I ended up buying my motors because the wires kept breaking on the ones you can get in cheap vibrating toothbrushes.
- Take the two motor wires and tape each wire to a side of the battery using masking tape. I like masking tape versus electrical tape because it sticks a bit better as you pop the motor into the pumpkin. Motor doesn’t turn on? Switch sides… Then slide one wire out until you are ready to play with the pumpkin.
- Now start up your motor by taping both wires to the battery. Then insert into the bottom of the pumpkin and let it motor around. It might take a bit of trial and error to get the brush placement just right, but this develops valuable engineering skills in your kiddos. There’s no success without failure :)
You have to watch them run around in this video. They’re so cute!

Cool idea Anne! I had to say when I first saw the pumpkin – I thought it was real and was wondering how you got it to move! Okay – gotta look for styrofoam pumpkins – neato!
So awesome! Love all your creative Brush Bots :)
Thanks!! We love building them.
I love these! I have an old electric toothbrush just waiting for this project :)
Thanks! We look like we have a toothbrush problem when you see our craft closet ;)
How fun! We just built a brush bot at home that looks very much like yours :)
Thanks! Ruh roh… I hope they weren’t for a post :P I hate it when that happens.
:) How fun! What a neat idea!
KAYUTE!!!!
And brainy.
Thanks!!! :)
This is such a fun idea!
Thanks Erica! We had a lot of fun making & playing.
