This isn't so much a toy as it is a tool, but I wanted to share it, as it'll be something that'll improve toy photography. I got a Micro Fogger 3 Lite, from Vosentech.
https://vosentech.com/ The name says it all, it's a mini fog machine. So I'm going to play with it for a while and write a review on it, probably by the new year. I have some lights, tripod and some figures that'll look especially cool with smoke effects. $140 for the kit is a lot, and I've been struggling whether to buy it or not, so we'll see if I was stupid or not.
