Sorry, another omission concerning the rules for the Cartesian Diver Event:
Rule A of competition and scoring should read " The team will have up to 10 (ten) minutes to complete the event".
The allotted time will depend on the number of bottles (up to 3) containing Cartesian Divers that the team must retrieve.
I understand we are past the last date to ask questions, however, regarding the Cartesian Diver event: I was wondering if the maximum mass of the sinker could be specified. Thank you!
I do not know the mass yet. I still need to construct them. In the past, I have used the top (bulb) of a plastic pipet (the inexpensive types used in chem classes) with metal wire and some washers as weights.
Also, 1/2 inch tape is hard to find and 3/4 inch tape is the most readily available one in stores. Would it be acceptable for students to use the 3/4 inch tape for newspaper bridge and the boomerang events? Thanks in advance!
