Picture of Robo-Pumpkin!
This Instructable will show you how to make a pumpkin that moves and glows in the dark!
I got my idea from evil mad scientist laboratories. They used LEGO to power there pumpkin but I found some cheap gears and axles from the k'nex company. Over all the build was a success!

Happy halloween!

Step 2: Cut the pumpkin

Picture of Cut the pumpkin
start by cutting of the top, about 5 cm down from the stalk of the pumpkin. (cut off the stalk, we wont need it) and then hollow out the insides with a spoon.

Note: I have cut the top of and not used it because we won't need it for this Instructable.

Step 3: Motor

For this step, you will need to glue the bottom of your motor to a piece of correx about 20 by 10cm wide.
Next stick it down and hold it in place with duck tape.

Step 4: Motor

Thred the red rod through the motor and stick a black ball joint on the end.

Step 6: Gears

For this step, you will need two green rods, 2 yellow or grey rod connectors and a small gear cog.
First connect the two green rods to the black rod connectors like shown in the picture. Then connect the yellow/grey rod connectors to the green rods like shown in the picture.

Finally slide the small gear cog on to the red rod you put there in step 5

Step 7: Wheel axel

Put a solar motor on it so when kids have flash lights it runs right towards them
Cool project, I made one like it last year with a remote control car, except I used a fake pumpkin.

Sweet it can run away when punk kids try to smash it.

Sometimes the punk kids soil the pumpkins, if you know what I mean.  Then they just pick it up and fill it with said load and then they set it down somewhere where it can drive around and smell bad.  It needs to have a load detection device and an internal cat litter dispenser or something to push the load back out or better yet a small explosive to destroy the nasty pumpkin and its contents or even something to stop said load from entering pumpkin in the first place possibly even a catapult to throw it back at the dispenser of said load.
