Everyone knows you can't build a rocket without McMaster-Carr. But can you build a rocket from only the McMaster catalog?

I'm running the McMaster-Carr Rocket Challenge. Hopefully I'll see some entrants that leave the ground and win prizes! Prizes are awarded twice a year (at present; that might change). Which prizes will be awarded? (Dates listed are submission deadlines; prize award dates are a bit TBD.)

Award dates will be added or changed only after the dates listed on this market.

As the contest operator, I will not bet on this market and will not submit contest entries. I might post an otherwise-qualifying entrant, but it will not be counted for this market or for the prize.

Current prize pool is $3720.69.
