These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Franny K. Stein
Fridge Logic: Considering how much property damage Franny's experiments have caused, how has her family ever managed to pay for it all? I can only assume Franny got patents for some of her experiments that actually did work.
