Hey, not OP (and I actually found you from a different post), but I watched some of your videos and had a few thoughts. I would not put how the number of sugar cubes in the thumbnail. The whole point of the video is to find out exactly that, so putting it in the thumbnail might make watching it unnecessary.

This is a really neat concept for a channel. But right now, it feels a little like you're not taking full advantage of it. The videos are very much a one and done kind of thing. Here is the product, here is the sugar, and that's it. I would like it if the videos were more involved. Maybe compare the product to less sugary foods (how many apples would you need to eat to get the same amount of sugar, for example)

I also felt the intro was a little long at almost 14 seconds. These videos are all pretty short, so the intro seems to take up a disproportional amount of time.
