Youtube destruction always has a delta value of what was destroyed compared to the income gained. For example, destroying an iphone in a blender might set you back 500$ but might earn you 1000$ in exposure, so the delta is +500$.

Crushing gold possibly has one of the lowest deltas of the kind, given that selling 24k gold of 99.9+ purity will get you near spot price - at any form. Practically, it's all profit from Youtube exposure / ad revenue.

Having said that, I think old washing machines where they throw bricks in them so that they can "die" in agony in some backyard, have the best positive delta. These will probably allow their owners to buy new ones ahahaha...

Good point Alex!
