Everclear
Everclear is a potent type of grain alcohol, that is available at concentrations of 75.5% alcohol and unbelievable 95% alcohol (190 proof, the highest proof alcohol that can exist without evaporating). Just to compare with some other hard liquors such as rum and vodka, which typically contain 40%–60% alcohol.
Because of hes strength it became popular amongst college students.
Its banned in some states, but in those where is legal to buy it, you can find him in 750ml bottle for just over $20, what is very good price for hes strength.
Everclear is commonly added to a variety of other drinks, such as soft drinks, energy drinks, fruit juice, and iced tea. Everclear is also used in cooking because alcohol extracts flavors exceptionally well. It is used to make custom liqueurs such as rosé or limoncello. It is infused with fruit and then diluted with simple syrup to 30% alcohol

Absinthe
Absinthe is also one strong alcohol drink, with 50%-75% of alcohol. Actual content varies by brand. For example Hills Absinth and King of Spirits Absinth a contains 70%.
Most absintheurs drink absinthe the traditional way: louched with water poured over a cube of white sugar. Some drink absinthe that was poured over sugar that is subsequently set alight (though absinthe purists decry this practice), and a few even like drinking absinthe neat (brave souls!). Absinthe cocktails, too, have long been a favorite way to enjoy this special drink. More recently, absinthe even found its way into ice cream sundaes and Swiss chocolates.
Absinthe has long been believed to be hallucinogenic, but today it is known that absinthe does not cause hallucinations, especially ones similar to those described in 19th century studies.
Like Everclear and Absinthe is banned in lots of countrys.
