It's like interdimensional cable but for internet forums. In my version of reality, we get completely naked when taking a shower, not just our hands. We have these kind of lay-down-showers called baths too, but that's a whole other thing. Also, the chemical element with atomic mass 207.2 g.mol ^ -1, which may seem like a useful building material, especially for shower pipes, is actually dangerous to life that is based on the chemical element 12.011 g.mol ^ -1. Figured I should include that in case OP's reality hasn't figured that out yet. In exchange, consider sharing something dangerous your reality has discovered that might not be obvious to us yet.
