The dying wheel is just a motor attached to knex. The attaching is trick but it's fun to make if you are bored.
1. Motor I used one in a case it is a bit hard to use one without.
3. Box of the smaller knex
4. screws if you have a motor case.
To start make the knex as I did the pics will show how.
It should look like this when you finish.
Next add the people who will fall.
Then screw the motor on to the sticking out area.
Add the on off switch and battery compartment to the motor.
Go to an elevated area and turn on the battery compartment. At this the knex will turn upside down and the two knex substitute people will fall.
Hope you liked it please fav and follow.
