Moon Fact

In diagrams, the moon looks like it is quite close to the Earth, it looks like it is within the diameter of the earth. The truth is the moon is approximately 380,400 kilometres away.
The distance between the earth and the moon is so vast that every planet would fit in the space between them.

Dehumidifier Credit

If you buy a good Dehumidifier that can remove more than 12 liters of Water per day, it will pay for itself in less than a year. During winter months it will reduce your heating bill because dry air is better at storing heat than damp air and feels warmer so you feel compelled to turn down your thermostat. 
It could also reduce the amount of time your sick from off work because dry air carries less microbes and viruses. 

It can also stop damage to walls and furniture cased by condensation.

Chromosome 2

In humans, Chromosome 2 is actually two chromosomes fuzed together. Most chromosomes are X shaped but they're only like that when the cell is about to split into two. Normally they are just a single thread of DNA. For some reason we have one Chromosome that is two fused together. 

There are telomere sequences in the middle of the Chromosome, they usually appear at the ends of the Chromosome.

Bombadier Beetle

The Bombadier Beetle has a biological weapon, their backside doubles as a gun. They can shoot burning hot acid out of their backsides to give predictors burns and put them off hunting them. 


The Bombadier Beetle does this by mixing Hydrogen Peroxide and Hydroquinone together in a chamber inside their abdomen. The two chemicals are present in separate glands in their abdomen but when they're mixed together they become a hot explosive acid.

Train Vs Taxi

If you were going from farringdon in London to Brighton, what is better? Uber or Train. 
If four adults were travelling together, the prices would be about the same.

A taxi going from London to Brighton costs roughly £100 (£25 each). 
A train ticket for 4 passengers going from London to Farringdon would cost about £100 (£25 for each passenger) 
If you had fewer passengers, the taxi would still cost £100. It would only be the same price and slightly more convenient if you were going as a small group. 

This observation doesn't account for rail cards and discount codes. 

Trains move a lot faster than cars and they sometimes give you cheaper return tickets, however some Uber cars can take more than 4 passengers, some can take 6 or 7.

Fizzy Fact

Most Fizzy drinks have carbon dioxide dissolved in them. The reason they chose that gas is because it has the most  positive attributes for the lowest cost. Carbon dioxide dissolves the most without making the water poisous. Ammonia dissolves in water more than carbon dioxide but it makes the water slightly toxic. 

There are other gasses that can be added to flavoured water to make it fizzy and not toxic, you can add oxygen or nitrogen but they have their own issues, oxygen fizzy water tastes flat and makes the water taste oxidized.

Nitrogen gas costs more than carbon dioxide and it is more difficult to dissolve in water so it makes the water less fizzy and the bubbles are smaller so the foam caused by pouring the liquid lasts a long time. Some beer companies have been known to use Nitrogen instead of Carbon dioxide because they don't want a tangy taste and they want the pouring  foam to last a long time. 

Most carbon dioxide gas in fizzy drinks is a by-product of other industrial process so it is very cheap. They almost treat it like a waste product, yet for a fizzy drink it is the best gas to use, you get more fizz, a tangy taste from the drink and you get a longer shelf life because carbon dioxide is acidic when dissolved in water and that kills microbes.

Pier Trains

There are three piers in Britain that are known to have working railed trains running on them. The most famous one is Southend on sea. The pier itself is extremely long 2.15 km (1.34 miles) and the train will take you most of the way across the pier. They claim to be the longest pleasure pier in the world. From my experience, the starting platform at the beginning of the pier has the look and feel of an old subsurface metropolitan subway station. 

The Ryde Pier on the Isle of wight has a more practical pier train. It is used to bring people to the catamaran ferry that goes back to the mainland and the bring people from the ferry back to the coast.

Hyther pier in Hampshire is the oldest working pier train line in the world.
