How to build your own bottle rocket
This Fourth of July, let your kids make a bottle rocket that's a whole lot safer than fireworks. All you need is a water bottle, some baking soda and vinegar, and you'll have a craft that's ready for takeoff.
- Empty 2-liter plastic bottle
- Colorful tape
- Baking soda
1. Decorate the bottle
Use colorful tape to decorate the outside of the 2-liter bottle. Use markers to add extra designs to the tape to give it a patriotic theme.
2. Make the baking soda packet
Pour about approximately 1 tablespoon of baking soda onto a tissue. Roll the tissue tightly around the baking soda, making a small bundle that is small enough to fit through the opening of the bottle.
3. Mix it up
Fill the empty bottle approximately 1/4-full with vinegar. Drop the bundle of baking soda into the bottle of vinegar. Working quickly, place the cap on the bottle and place the bottle upside down on a flat surface outside.
4. Watch it launch
Now stand back and wait for the rocket to take off! This can take anywhere form 30 seconds to a couple of minutes, so stand back until the rocket has launched.
