I had to check each part to see what the deal was with the power cord. You are correct, it happens to be in part 4 where she builds a cord of death.
Not very smart on her part or even the people making the video.
The cable SHOULD have been hard wired directly instead of the method that was chosen.
I agree, it should be removed from the video.
If you read ALL of the comments below the video most everyone agrees that it should not have been done that way. Plus her neighbor was the one that recommended it be done that way and he works on power lines. YIKES
As it turns out she plans to change out the cable to one that is safe to handle. Not sure what method she used as it was never stated.
