Cool timelapse, but which I also wanted to share because people in the comments are criticizing the op for sowing the seed "wrong" and "upside down", despite this being a video of it working fine.
There is no wrong direction to plant a pumpkin seed! The effects of seed orientation have no discernable impact on the long-term performance of the vine.
If you're a new gardener and somebody on the internet makes it sound like your season is ruined because you didn't take care to plant your seeds at the right angle, don't worry about it! They're vastly overstating how much it matters.
