here are instructions for the Elevating Head Element. This is a big and fun 2 in 1 element that is really easy to build. There is a humanlike head hanging in the middle that moves its eyebrows and mouth when a knex ball enters the head. The knex ball is then leed to a second element that lifts the entire head up. It works about 90% of the time.
If you are intrested in building this element, I recomend you to klick on this link:

If there are any questions, complains or problems, please tell me in the comments below.
Thanks for watching/ building,
