Drink Responsibly
It is important to make note that beer and soda bottles are under pressure. The pressure is around 40psi. This means that if the glass is damaged when the bottle is still capped, there is a possibility the bottle would explode. SO, if you are going to toast a friend by hitting two bottles together, be sure the cap is off. Without the cap, the bottle contains no pressure, and it will not explode if the glass is damaged during the toast.
