I have tested a bottle of this type with 100 kV, DC, and it didn't
break. But this plastic deforms easily with heat, and someone said
on this list that it is rather dissipative at RF frequencies. Add
power, dissipation, and deformation and you will have serious problems.
But has someone actually tried to make capacitors with these bottles?
