Has anyone else seen tracks where the marble rolls uphill, after completing a jump? All of the iterations my students have built have been strictly downhill (with the exception of small upward curve to change the launch angle) - but I suspect that with some impressive engineering, you could take fuller advantage of the potential energy allowed by the height limit.
I never seen tracks where the marble rolls uphill, but the video is quite fascinating!

If you were able to make a jump that decreases vertically, but then use the momentum to return the vehicle to almost the same height, the amount of gap distance you could achieve would skyrocket. However, I'm not sure wheather or not it could be done to a great sucess, just because of the restrictions on the dimensions of the coaster.

So this might be an obvious question, but based on my thought of design, how many balls can we use? Because we can't use any other energy (electrical) sources, can we make mechanical systems recreated by balls, but using 2 balls?

No. In the rules it specifies there can only be one vehicle.

one more question;
i dont have the copy of the rules on a paper, is there a printable for that?
Also, is ther a gap limit? this might be on the rules, but i dont have it so :p
okay thanks

There can be a maximum of 5 gaps with any length and you can find the rules by searching 2018 science olympiad division b rules on google.

You can get the rules from the national website:
