Did a stupid thing about 40 years ago I started making my own soft plastic worms and we just had single molds that you would turn over to see if they were ready to take out. I feel sure some have guessed already what happened. I had several molds poured and happened to forget which I poured last so I picked the one I shouldn't have and turned it over and that hot plastic ran between my fingers and that was the end of my making my soft plastic worms, LOL!
