I cant find anywhere to buy saltpeter, ive already gone to a few different pharmacies. Any suggestions?

Understanding Physics by Isaac Asimov is a great book on physics that covers a lot of topics.

The only thing that I can think of that generates 40,000+ volts is a stun gun. Somehow they use one or two nine volt batteries and convert that into 100,000+ volts.

There is no constant speed in which bodies fall to earth (unless acted upon an external force for example:wind resistance), however there is a constant acceleration(~9.81m/s/s) of falling bodies(in a frictionless environment )on earth.

why wouldnt the core collapse if your useing a rocket fuel like nitrate/sugar/sulfur ? Its like dust isnt it
