There’s a nice visual connect here between the path of an ice breaker and the effluent of a rocketship.
Re-Edit: Whoa – just realized, the boat picture isn’t an oil spill, but rather the path of an ice-breaker (even cooler)
Called “Beyond the Limits”, the effect you see here is pretty cool, although not really sure how these pieces might be used in a science lecture.
Possibly to do with carbon? (oil, exhaust, etc).
