This is my Rube Goldberg Machine that includes many items. Like, sheep, sand, gravel, water, mine carts, pistons, and many more items. It only takes about 2 minutes to get through the whole machine. It was very fun to make and there is a video you can see that shows the whole thing in action.

Extra Information:

-It may not work all the time, it can stop at an area
where arrows are shot but, it's unlikely
-It's sole purpose is to server you chicken
-It uses about 20+ items
