try soaking it in barium chloride, which gives fireworks their characteristic green

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.

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.

This recipe uses sugar..

Stump remover (the thing he used) is pure KNO3. SO YES.

Maybe, but marshmallows tend to stick. This creates pressure buildup, which tends to blow the marhmallow to pieces. Marshmallows also will get smothered by the rapid acceleration through the pipe. A simple solution would be to use a reducer smaller than the marshmallow, and a slightly larger pipe.

*acrylonitrile butadiene styrene

Consider removing your cap before you shoot it.

C12H22O11 + 6 KClO4 = 12 CO2 + 11 H2O + 6 KClDoesn't combustion of sugar with potassium perchlorate create potassium chloride? Or does the KCl decay further to produce thrust?

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
