Ground Hog Day Level 1-24 is solved in two steps using the same contraption. Build a three box cart with a fan and electric motor on each side, and the soda bottle between the wheels. Place the umbrellas above. Navigate your vehicle quickly using the fan and smoothing the landing with open umbrellas towards the finish line below within the time limit. The second step requires good timing to collect the star. Follow the same steps as above, but open the umbrellas as late as possible when leaving the ramp below.
