Re: Domino sizing

I agree on stability. We get around 85 cm stable, much past that things get wobbly. If you are going for the whole distance it must be even worse. We used a telescope, but I think a carefully designed scissor would be the way to go.

Re: Don't be 2nd tiered because of motors

... I agree that several questions in the clarification are removed and certain ones are kept, I have no idea why. Why not leave everything intact for everyone to see. Maybe it gets too prohibitively large, I don't know. hogger, could you please point to where you see the clarifications you discuss...

Re: Domino sizing

just re-read again, after studying it intensely before regional. seems like falling off is the only problem, so if you make the platform bigger and put the dominoes one domino width from the edge, and of course have a reasonably stable lift, it should be fine.

Has there been any official clarification on what happens if one falls off? We think the official at regional counted what was left on to...

Domino sizing

I wanted to call attention to this update to the domino size rule. We ground our dominoes for regional to meet the size requirements, and I am glad I caught this before the state competition.

Re: Mission Possible B

An interesting point here: I was convinced the judges would come around with a volt meter and test the voltage, but they did not. They go by the labeled voltage on commercial batteries. I was talking to a team that had timed using a 9v cordless drill battery that they decided not to run because it p...

Re: task c

The rules say that hazardous liquids are not permitted. Seems a stretch to classify water as hazardous in such a small quantity.
