--> For model 1, the boat was too heavy and this caused the boat to remain stationary. We needed a lighter boat in order for it to move.
--> For model 2, the boat is too small and sinks after the candles are placed inside. We needed a both light and sturdy boat.
--> For model 3, the boat did not sink but the amount of steam produced is not enough to power the boat. We could either use more candles or make a lighter boat, however, we did not have enough time to continue and these are our 3 models.
