Ethanol doesn't like plastics.
Yeah, alcohols make very
good solvents. In a relatively strong solution of ethanol, acrylic will literally dissolve into nothingness. You could use other plastics like HDPE or PET (see here
I would also expect ethanol to perform significantly worse than water - across the board, it's thermal characteristics (specific heat, thermal conductivity, etc.) are roughly half the value of those for water. Not sure what "advantages" people are spouting off but scientifically there is no evidence I see to support it. Interesting experiment though.
