Q: In regards to Zip event, when kids are in the competition room, do they have the opportunity to modify the cable car in between each of the runs (i.e. after the 1st and 2nd one) or just after the first two? The event description states they will have 2 minutes to modify after the first two runs, but is that the only opportunity for modification?
A: The students will only have 2 chances to modify the cable car (after the 1st run and the 2nd run). Since there are only 3 runs in total, there is no need for modifications after the 3rd run.
Q: For Zip a dee doo dah, does the ping pong ball need to stay in the carrier just between the photogates? (ie, if the ball falls out after hitting the end of the zip line, is that ok?)
A: Yes, the ping pong ball needs to stay in the carrier just between the photogates. If the ball falls out after hitting the end of the zip line, that is ok.
