The capacitors in the tutorial are rated for 330vdc; if the voltage is stepped to high, the capacitors will heat & explode. To workaround this get higher rated capacitors.
View Instructable »The capacitors can only handle 330VDC. Theoretically with higher-rated capacitors you might be able to step up to over 440V., but with these capacitors they'll probably explode, as the Unibrow showed us.

It'll show some random text characters or letters on their computer. Otherwise it'll give an error since VBasic is not availibly on Mac
If you think about what Wikipedia says, it makes sense. Any polymer chemist could verify this, unless you propose that every expert in the field is incorrect. Fancy wording is necessary to describe this form of chemical interaction. There is no reason to lie about this, anyhow.
