Question of the Day!

Yes, unfortunately people sue companies for end user dumb mistakes. It's just cheaper long run to have signs telling people not to replicate mistakes that had been either done during some lab R&D or by some Scientist in ages past.

I'd say ask Marrie Currie or the "Ghost Girls" who worked in the glow in the dark watch factories back in the early 20^th century. But that might be a little hard.

Fun fact: Marrie, and the "Ghost Girls" all died of radiation poisoning. Turns out substances like Radium are even more dangerous than modern glow sticks.
