How to make a rocket

Materials required
1. A Bottle
2. A Cork that will fit the bottle tightly
3. A Cardboard piece
4. Baking Soda
5. Water

How Do I Do It

2. Pour lemon juice and mix it with water
3. Put baking soda into the bottle and fix the cork on it tightly
4. Shake the bottle well and keep it down
5. Go back a few feet and see what happens

What Will Happen And Why
1. The cork will shoot through the air with a big blast and will fall down
2. This happens because the baking soda reacts with lemon juice which is an acid and produce carbon dioxide water and salt
3. The carbon dioxide makes the cork blast out and fly
