Searching for an easily-obtainable black powder substitute?

I currently reside in the UK, and am not eligible to purchase black powder, due to age restrictions implemented in my constituency (15), and pondered the thought of obtaining a substance that possess similar properties in order to commence with my incomplete experiment.





If you have any knowledge of where a substitute can be purchased, please specify (preferably a well-known supermarket), otherwise I will be forced to trade online for it.Searching for an easily-obtainable black powder substitute?
Purchasing or trying to purchase black powder or other explosives is illegal for most people in the UK. Causing explosions certainly is!





Quite apart from that, if you have to ask the question, you almost certainly are not fully aware of the dangers and safety precautions, and might join the many others I've known over the years who have ended up minus fingers or a hand or worse. Other sources of things like sulphur are not always suitable for making what you want and may even bring unexpected hazards.





The anti-terrorist squad monitor sites like this for good reasons and are no doubt already tracking you down.Searching for an easily-obtainable black powder substitute?
Charcoal is a black powder so try that





But if you mean what I think you mean by 'black powder' then you must be joking!!!
