Arrange the following instructions on how to make a mini bottle rocket in order.
1. Wrap the baking soda up in the kitchen roll to make a little parcel.
2.When you're ready to launch, drop the baking soda parcel into the bottle, quickly add the cork, put the rocket down, and stand back.
3. Use tape to attach 3 straws to the side of the bottle so it stands up, upside down.
4. 5. Pour about 3cm of vinegar into the bottle.
Choose a launch area outside. It needs to be a hard surface.
