Exclamation Urgent! Project for Physics Class! "Air Train" of sorts.

Basically I need to build an air train for my Physics class that goes 30ft across a fishing line. It also has to be able to tow two objects at the same time. I'm allowed to use battery powered components in my vehicle. The fishing line will be pulled tightly across the length of a science lab. I have one idea. It's to use a remote control car. However, my biggest problem is how to get it on to a fishing line without restricting the forward motion of the vehicle. If you have an ideas on how to keep the vehicle on the line or any completely new ideas, please respond. All help is needed and appreciated.

How are you going to propel the vehicle?
If you are thinking of gripping the line with wheels and pulling the vehicle along the line that way, I think that might be difficult.
fishing line is small and quite slippy so it will be difficult to get traction upon the line.
however if you use a propeller, or a jet (or rocket) the slippiness of the line is useful
then you can just hang the vehicle via (metal) hooks under the line.
