quote:Originally posted by DoctorBeaver Synthetic Phonics. What an amazingly innovative idea that is. Who would ever have guessed that children who learn the sounds of letters would be able to read better than those who don't? My primary school must have been way ahead of its time because that's how we were taught in the 50s!
quote: I think that you're right, there's a lot more for people to know these days compared with 50 years ago. Just take a look at medicine - hospitals once had medics and surgeons, now they have about 30 different medical sub-specialties and surgeons who only operate on aortic aneurysms.

Originally posted by weebraingunpowder:-75 per cent potassium nitrate (salt peter)5 per cent charcoal10 per cent sulphurThere are quite a few sources of saltpeter including bat dung, animal and human urine, and tobacco stems.The old saying "keep your gunpowder dry" was a comment on the fact that saltpeter will dissolve in water. Get your gunpowder wet, and when it drys, most of the saltpeter is gone, and the powder won't work.Grind the charcoal and sulfur seperatly, and mix these two dry. Dissolve the saltpeter in water and mix wet with the charcoal and sulphur. Spread the paste out on a flat drying surface about 1/2 to one cm thin. When dry, crumble with your hands. Do not crush with a hard instrument unless I have previously purchased an insurance policy on your lifeDavid
