I would like to see a follow up test for example. Do the liquid metal to 5 laptops, then have 5 people use them as a daily driver for a week or month. Then open them up and look at the results internally. For even more variants (I know Linus loves those variants) use nail polish or other sealants around the DI and for sure one that has none of that stuff using only hubris to keep the liquid metal in. I for one, would really enjoy seeing that sort of thing (mostly cause I want to see a laptop die from this).
