Today I want to tell about Flora in USA Great Britain and Kazahstan.At first sight(с первого взгляда) , I thought that there are practically no Flora.But I was mistaken.There are a lot of Flora there.I will name some.
In Usa there are a lot  of berrys, some dwarf willows and there are birchs.
And some cereals
In Great Britain there are a lot of forests and beautiful flowers.For example wild daffodil, lilies, purple orchids and primroses. 
In Kazahstan there are a lot of forests too.But Flora is not very big because half a countrie is sand.Also there are some flowers.
Thank you for you attention!

The invention of super glue is a quite interesting fact. Nowadays it is almost impossible to do without super glue:  either a handle of your cup broke off, or your shoes got ripped, or the plinth fell off. In these and many other cases The Super Glue is our only lifesaver.

So how was it invented? Back then it was considered a really big discovery, which was accompanied with various myths and legends, as per usual. You won’t believe it but for a quite long period of time it was widely believed that this glue was primarily intended for gluing the wounds.

It is rather weird assumption, but quite explainable, as the glue was discovered during World War II by American scientist. By the way, it was a pure accident:  in a search for materials to make clear plastic gun sights, a team of scientists stumbled upon cyanoacrylate that stuck to everything that it came in contact with. This discovery occurred to be very useful and was patented in 1995. In 1959 it was already being shown on TV.

For a long time the Super glue had been showing up on different American talk-shows, where its new fascinating features were discovered. Cyanoacrylate could glue together anything, even unprotected surfaces. The crucial problem of this glue is not gluing things too tightly, but the impossibility of separating them afterwards.
