Use a button battery and cell phone vibrator motor (provided by Joe) and create a device that is propelled only by the battery and motor. Must be under 30mmx60mm. Must not contain sticky or stringy entangling things. You have 1 hour to build 1 or 2 devices. After the hour we will race them 1 on 1 (each team only gets to race 1 device per Challenge). Then a poll race with 1 device from each team at 1 time. After that Monkey in the Middle – All bots will start at the center of the table and the first one off the table is the winner. Then finally Poker. Cards are placed on a table and your bot picks your team’s best 5 card hand.
