Here are instructions for a really fun knex element. This is personally my favorite one from my latest knex ball machine called Pluto.
Make sure to take a look at step1 to see what special piece you need to complete this build.
This element uses 1 of those newer (slightly larger) knex balls. If you don't have one of those you can just replace it with a classic one. It works just as fine.
You can watch the video above (9 New Knex Elements) to see how it works.
Thanks for watching/ building,
