In a parked, unmanned car, the cap on a plastic soda bottle pops off and the cola fizzes out. A plastic toy puppy sags and topples over. A chocolate bar and gummy candies melt into slime.

These eerie images of what happens in a parked car under the scorching sun, shot by Nissan Motor Co., is part of the automaker's "No more #CarHeatStroke" campaign, started Aug. 4. The 70-second clip, uploaded on Nissan's official YouTube channel, has gone viral, viewed more than 330,000 times so far.

"If the weather outside is 35 degrees Celsius, it means the temperature inside a parked car is over 70 degrees," the automaker states on the video. "Leaving kids or dogs in this condition, even for a short period, means their lives are in danger."
