Funko Pops, to me.
I understand that some of them are fairly overpriced, but I also really like them as is. It doesn’t work on all characters, but it sometimes work on a lot and there’s so much representation and variety that it’s good to have a few.
If people want to talk about waste of plastic and vinyl, they should bark at the companies who make teeny tiny figurines that serve no purpose and have so little detail that spending any money on them is a waste.
Microwaves are ~2.4GHz, same as wifi. That is the resonant freq of water. They don’t go deep, not even close to a milimeter. And it all converts to heat.
The sun is more damageing then microwaves of same power. And ionizing radiation is the really harmful one.
