Science Hack: Easy way to clean your silver
To a cup of hot water, add a tablespoon of bicarbonate of soda and a ball of scrunched up aluminium foil. Drop in the tarnished silver and leave for a few minutes, then rinse. Now for the science bit... the black tarnish that forms on silver is silver sulphide, the aluminium foil reacts with this to create aluminium sulphide, turning the tarnish back to silver. The foil is coated with a layer of aluminium hydroxide which the bicarbonate of soda helps to remove too!
Science Hack: Stop crying over your onions
When you slice an onion, a chemical reaction occurs between enzymes and chemicals to form a gas. This is what produces the potent smell of an onion, and is also to blame for the tears and the stinging sensation in your eyes. However, onions that are chilled for 30 minutes before chopping give off less of this eye-irritating gas that makes you tear-up because the lower temperature inhibits the chemical reaction!
Science Hack: How to identfy a bad egg!
Fill a jar with water, if the egg sinks and lies on its side, on a point or at an angle it’s fresh. The older the egg the more vertical it is, if it floats to the top, it may be a bad egg! It may not be rotten but it won’t be fresh. Why is this?
When laid, eggs have an air sack that increases in size at is gets older. Eggshells are porous, as they age the sack cell fills with more air increasing its buoyancy. Hence, the older the egg, the more air it contains enabling it to float in the water.
