Two thousand years ago, a cook mixed three ingredients very common in any kitchen: potassium nitrate (food preservative), sulphur and charcoal. Mixed and and heated, they go off exploding on a huge bang. This is basically gunpowder.
Why is water not blue?
Water is blue on its own. Any object shows a given color because it is absorbing visible light from some other wavelength preferentially . Water has a weak absorption band in the red part of the visible spectra (close to the infrared zone). For this reason, water shows a blue color. Since this red absorption band is so weak, we can only observe the blue color if we have a massive volume of water. That is why water in a glass appears to be colorless, but bigger volumes such as oceans, lakes, or swimming pools, are blue.
How to get carbon dioxide out of a candle?
You can generate a lot of carbon dioxide gas by mixing vinegar (acetic acid) with baking soda (sodium carbonate) in a glass.
