last Saturday, I made a cup of lemonade myself. First I cut the lemon in two. Then I crushed two cloves of lemon. After that I got a cup of lemon juice. Then I put some water and some sugar in it. At last I put sodium bicarbonate in it and close the lid. Then I shaked it and the lemonade was done. But it too sour and salty. I'll do it better next time.
