DO NOT EVEN JOKE ABOUT MAKING NITROGLYCERINE.

That isn't nitroglycerine but guncotton, different things.

IN ANY CASE, YOU WILL BE COMMITTING A SERIOUS CRIMINAL OFFENCE IF YOU
ATTEMPT ANY OF THE ABOVE.

Criminal?

Yes! Guncotton is an explosive and when fired it detonates- i.e. it burns at
a rate of more than 1000m per second. It is thus classed as a type 1
explosive and to manufacture it you need a 'mixing license'. To manufacture
it without a license is a criminal offence. Black powder (gunpowder) and
fireworks burn at a rate below 1000m per second and do not detonate (produce
a shock wave) but deflagrate and it is not illegal (although not advised) to
produce them.
