When Square Numbers Multiply Themselves With 2 - 1 to 40

In this video, numbers from 1 to 40 will show themselves as they're squared.
And after they show their squared selves, their squared selves will show themselves when they're multiplied as times 2.
This is a combination with 1 to 20 and 21 to 40.
Reuploaded because originally, I got an error as 196 x 2 = 162. The correction is 196 x 2 = 392. And 676's times table was the same as 21.
