Bottles will explode if you do not let the primary fermentation finish fully. Because there will still be left over fermentable sugars in the brew when you bottle them, adding more sugar at the bottling stage will cause the bottle to over gas during the second fermentation and explode.
Also adding to much sugar when bottling will cause them to over gas and explode.
For the second fermentation, try and find an old Kelvinator fridge from the 60's and put a 40wtt light in it. Thats what I use cause its way too cold down here in geelong, and I cant be assed waiting weeks for a brew to be ready.
Use longneck bottles, cause then you have to clean half as many as you do when using stubbies (a big bonus) and make sure you rinse out every bottle after you've drunk them so that they dont grow mold, saves a hell of a lot of time in the long run, write down all the recipies, and save a couple of bottles from each batch so you can drink them in a years time when they're 10x better.
and most of all, enjoy it. Its great fun getting plastered, but its even more fun when you're enjoying something you've made yourself. And it tastes better than almost any commercial brew you can buy.
saying that, me and my mate just bottled up about 45 litres last night.
