lokolobos right, but i just wanted to go a little further with that, you dont nessasarily have to melt it together, you can just mix the salt petre and sugar and burn the powdered mix. there are ups and downs to each way though. its alot harder to burn the powdered mix, but melting the mix can be kindof dangerous. either way, take precautions whenever messing with flamable stuff. wear flame resistant gloves, clothes and always wear eye protection. if you want to go one step further, wear hearing protection just in the small possiblility of a boom. (though, with this low flamable mixture, you probably dont need it, its your choice.)

For about $100 you can buy a smoke tube kit. These are 3 inch long tubes which contain a chemical which reacts with air to create a white smoke.

Pumping air through the tube with an aspirator bulb generates a small puff of dense white smoke. These are used in testing of HVAC systems for air flow

It is fine to supplement formula with breast milk, people do it every day and it is probably because they want the baby to gain weight a little more rapidly than what it is. If you feel like you don't want to supplement with formula there are packets that you can mix with the milk that adds calories to your breast milk to help the baby gain weight. I would give a "sponge" bath to the baby until a few months old because he will still be relatively small and that is what I did with my daughter. You should not take the baby out to public places for the first few months if you can at all avoid it, his immune system isn't as strong as a full term baby. By the first year of life your preemie should be caught up to other one year old children. Just treat the baby with love and he will be just fine.

You can make smoke by melting 1 part sugar and 1 part salt peter together.. then once it's hard you can ignite it to make smoke.. Be careful though because when it is burning it burns like a flare or torch..
