What experiments can I do with these chemicals?

yes you would have a slightly poisonous vinegar but it would make a great disenfectant, it probably would kill 100% of all germs............but it kind of sounded like you wanted to make fireworks or a bomb since you bought potium permangenate, denatured alchohol, copper sulphate and copper chloride............if you mixed the permangenate with some type of combustive metal, the powder would be flammable, try mixing those two in a ratio of 5/7 and then add the copper sulphate and copper chloride and you will have a colorful bomb if you put it in some kind of closed tube with a fuse...........ps try mixing the potium with some magnesium or aluminum powder 400 mesh or up...............good luck!!!
