materails:
Hydrochloric acid
Plastic 600ml bottle
aluminium foil
Put hydrochloric
acid in the plastic bottle (but be careful because that stuff is very strong and it could make you faint)
Next step: Scrunch up little pieces of aluminium foil so there is about 6 or 5 little tight balls of aluminium foil
Next step: Go to a good location to let off the bomb and put in the aluminium balls (dont rush so much though because nothing will happen yet because the cap is not on)
Put on cap and shake a bit for 1 sec and throw get a least about 100 metres away
This makes a very loud bang and the neighbours might get worried. After you've thrown it, it would be a good idea to run as far as possible away from it so people wont suspect you
