There are different types of obstacles which can rotate after been hit by marbles. Most rotating obstacles are mounted on a pin inside the sand course, sometimes a wooden board is placed over the sand to reduce the chance that a marble will get stuck in front of the obstacle.

The rotating obstacle can push away marbles after been hit, marbles have better to avoid these nasty things.

Spinner / Mill: Edit

This little wooden spinner has 4 wings and will simply rotate upon hit. Because of the little dimensions, it won't be a really threat unless been placed in the middle of a narrow course.

Rotating Chevron Sign: Edit

After been hit, this sign can swing away the oncoming marbles. It will be placed usually on wide track sections or in front of splits or other obstacles.
