This is [[Forest Hills Central High School]]'s Action Sequence List from MI State 2018. The device was constructed by users Tesel and Rezalis. Included are photos and detailed build/code information about each task.

The device scored 1st place at the MI State competition. The score was ~1505 points with a target time of 67 seconds. The device completed all tasks, measured at 30 by 30.5 by 31 cm, and ran for 105 seconds with a chemical timer of 90 seconds.

|Aluminum foil connects with another piece of foil, completing a circuit. Completed circuit triggers arduino, which powers 40W electric heater inside ¼” compression fitting. Gas inside the fitting expands due to the increase in temperature, forcing water out of a capillary tube. Water drops onto a water sensor.
