Welcome to another head element instruction, and this time I show you how to build the mouse head element. When a knex ball enters the head the eyes, ears and mouth moves. You can always watch the video to see it in action. You just need 2 special pieces to build this element (see step 1).
If There are any problems/ questions feel free to ask me in the comments below.
Thanks for watching/ building,
Step 1: Special Pieces You Need.
You'll need 1 of those orange pieces and 4 of the black ones.
