sorry, this is a bit off topic, but reading this thread reminded me of a tale from my uncle's childhood. He once built a model plane, of the balsa and tissue variety. Unfortunately, during construction, one of the wings became slightly warped, and the plane never flew straight. Eventually, he became fed up with the model, to such an extent that he placed one firecracker inside the fuselage, and one in the wing. My father was present on the day of this aircraft's last flight, and he recalls the spectacular sight of one firecracker removing the flimsy wing quite effectively, leaving the burning fuselage to spiral earthward, only to be destroyed by the second firecracker moments later.

I have never heard of terrorists using Potassium nitrate. It is ok to buy it over the internet.

Usual response to this question (you are the latest of many many many people to ask this) to buy from Garden Direct. Searching, either this forum or google will come up with their website. Who knows, perhaps they are within driving distance and you can buy from the store.

Don't pay more than a few pounds per kilo, you are being ripped off in an epic way if you do.

Have you read this entire thread?

It is a decent task but you will learn a lot if you do. You will learn things you would never have thought of asking.

Good luck with the special branch anti terror cops, they are known to be watching this forum.

Kinda joking, they might be, but they are kind to us. They are our friends.

Relax :blush:


reading this thread in its entirety is a task of epic proportions, but I intend to eventually.

this may be the wrong thread, but I just wanted to propose using a golden syrup tin as a mill drum, the main advantage(apart from me having about 10 of them lying around) is that the lid would easily pop off from internal pressure, hopefully eliminating the risk of explosion due to accidental ignition. what do you guys think?

sorry to divert this topic, This question has probably been asked before, but I'm having trouble finding OTC KNO3, (the way this country's going i'm reluctant to buy online for fear I'll end up with special branch at the door), any tips on where to find it?
